## Career and appointments

Chen completed his PhD at the Institute of Metal Research of the [Chinese Academy of Sciences](https://www.edgepedia.org/chinese-academy-of-sciences) between September 2002 and July 2008, supervised by Professor Hui-Ming Cheng and Professor Gaoqing (Max) Lu.<sup>[2](https://chemeng.uq.edu.au/profile/3742/zhi-gang-chen)</sup><sup> • </sup><sup>[3](https://orcid.org/0000-0002-9309-7993)</sup> He then moved to Australia, joining UQ's School of Mechanical & Mining Engineering in January 2009 as an ARC Australian Postdoctoral Fellow, later holding a QLD Smart Future Fellowship and a Senior Research Fellowship there until September 2016.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup><sup> • </sup><sup>[3](https://orcid.org/0000-0002-9309-7993)</sup> According to his QUT academic profile, a Queensland International Fellowship in 2012 supported a four-month thermoelectric research visit to Caltech, and he returned for two months in 2013.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup> 

The move to professorships came in two steps. He became a Professor of Energy Materials at the University of Southern Queensland in 2016, and joined QUT as Professor of Energy Materials in December 2018, a role he held until December 2021, when he took up his current Capacity Building Professorship in the School of Chemistry and Physics.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup><sup> • </sup><sup>[3](https://orcid.org/0000-0002-9309-7993)</sup> UQ appointed him Honorary Associate Professor in 2016 and Honorary Professor in 2020.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup><sup> • </sup><sup>[2](https://chemeng.uq.edu.au/profile/3742/zhi-gang-chen)</sup> He was appointed an ARC Future Fellow at Level 3 in 2022.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup>

## Research on thermoelectric materials

[Thermoelectric materials](https://www.edgepedia.org/thermoelectric-materials) turn a temperature gradient into electrical voltage, and can also use electricity to move heat, so the same physics underlies waste-heat power generation and solid-state cooling. Chen's group works on thermoelectrics for power generation and cooling, next-generation optoelectronic devices, topological insulators for chips, and high-speed sensors, with expertise spanning sustainable functional materials, advanced manufacturing, and advanced microscopy.<sup>[2](https://chemeng.uq.edu.au/profile/3742/zhi-gang-chen)</sup><sup> • </sup><sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup> According to his QUT profile, he reports world-record ZT values in several thermoelectric systems and energy-conversion efficiency above 15% in a developed system.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup> 

A recurring theme is the silver copper chalcogenide family (AgCuQ, where Q is sulfur, selenium, or tellurium), which a review he co-authored in *Advanced Materials* attributes to inherently ultralow lattice thermal conductivity, controllable electronic transport, strong performance across temperature ranges, and a degree of ductility.<sup>[6](https://doi.org/10.1002/adma.202313146)</sup>

## Representative work

His 2025 *Energy & Environmental Science* paper on manganese-doped polycrystalline AgCuTe reported a ZT of about 1.88 at 773 K, described as one of the highest reported values for AgCuTe-based materials and comparable to other state-of-the-art medium-temperature thermoelectrics. The enhancement came from band convergence and valence band flattening, plus reduced lattice thermal conductivity from intensified lattice defects. A single-leg segmented module combining the material with commercial p-type (Bi,Sb)2Te3 achieved about 13.3% [energy conversion efficiency](https://www.edgepedia.org/energy-conversion-efficiency) under a temperature difference of about 462 K.<sup>[4](https://pubs.rsc.org/en/content/articlelanding/2025/ee/d5ee02875b)</sup> A QUT press release described the manganese addition as making silver copper telluride the most efficient material of its kind, with a prototype device built to convert waste heat into electricity.<sup>[7](https://sciencesources.eurekalert.org/news-releases/1098776)</sup>

His 2026 *Energy & Environmental Science* paper reported a hydrogen-powered thermoelectric trigeneration system for homes that produces electricity, heat, and freshwater. According to a study in *Energy & Environmental Science*, it delivered an electrical output of about 50 W at roughly 2.5% thermoelectric efficiency, described as the highest performance reported to date for hydrogen-powered thermoelectric generation, harvested freshwater at about 0.2 kg per hour while recovering over 40% of flue-gas water vapor, and provided roughly 1.2 kW of thermal output for a combined heat-and-power efficiency of about 75%.<sup>[5](https://pubs.rsc.org/en/content/articlelanding/2026/ee/d6ee02588a)</sup> A 2025 *Nature Communications* paper from his QUT group reported record-high performance in ductile AgCu(Te,Se,S) thermoelectrics through strategic vacancy engineering.<sup>[8](https://www.nature.com/articles/s41467-025-58104-x)</sup>

## Recent developments

The 2024 to 2026 period shows a shift from materials records toward devices and systems. QUT ePrints lists a 2026 *Advanced Energy Materials* paper on rare-earth yttrium doping advancing high-performance AgSbTe2 thermoelectrics, and a 2026 record titled "Ionic Coordination and Hierarchical Architecture Enable Record n-Type Thermoelectric Efficiency in Soft Hydrogels", on [flexible thermoelectrics](https://www.edgepedia.org/flexible-thermoelectrics), with Chen as senior author.<sup>[9](https://eprints.qut.edu.au/view/person/Chen,_Zhigang.html)</sup> The hydrogen trigeneration work extends thermoelectrics from single-material efficiency claims to a full home energy system with quantified water and heat outputs.<sup>[5](https://pubs.rsc.org/en/content/articlelanding/2026/ee/d6ee02588a)</sup> In 2023 he received the QUT Research Excellence Award.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup>

## Recognition, funding and industry

His fellowship record includes the ARC Australian Postdoctoral Fellowship for 2009–2011, a Queensland Smart State Futures Fellowship for 2012–2015, the Queensland International Fellowship to Caltech in 2012, an Australian International Science Linkage Fellowship in 2010, and the ARC Future Fellowship in 2022.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup> According to his QUT academic profile, his grants include 5+ ARC Discovery grants, about 2 ARC Research Hubs, 3+ ARC Linkage grants, 3+ ARC LIEF grants, and more than 10 industry investments, totalling about A$40 million.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup> Industry interest and investments named on his profile include [HBIS Group](https://www.edgepedia.org/hbis-group), NQ Minerals, Cook Medical, BHP Billiton, and the [Defence Science and Technology Group](https://www.edgepedia.org/defence-science-and-technology-group), and UQ lists several commercialized patents that have attracted industry investment.<sup>[1](https://www.qut.edu.au/about/our-people/academic-profiles/zhigang.chen)</sup><sup> • </sup><sup>[2](https://chemeng.uq.edu.au/profile/3742/zhi-gang-chen)</sup>
