# Alexei Gruverman
**Alexei Gruverman** is an American-based physicist who works on nanoscale ferroelectric materials and is known for pioneering piezoresponse force microscopy (PFM), a scanning probe method for imaging ferroelectric domains (regions of a material with uniform electric polarization). He is Professor of Physics and [Astronomy](https://www.edgepedia.org/astronomy) at the [University of Nebraska–Lincoln](https://www.edgepedia.org/university-of-nebraska-lincoln) (UNL), where he holds the Mach Professorship in Physics and Astronomy.[1](https://directory.unl.edu/people/agruverman2) His laboratory studies nanoscale physical phenomena in electronic and polar materials using scanning probe microscopy, including ferroic domains, the scaling of ferroelectric devices, polar surfaces, SPM-assisted nanostructure fabrication, and the electromechanical properties of biocompatible materials.[2](https://gruverman.unl.edu/)

## Education and early career
Gruverman received his PhD in solid state physics from Ural State University in Ekaterinburg, Russia, in 1990.[6](https://physics.unl.edu/person/alexei-gruverman/) • [4](https://www.sfu.ca/isaf2011/Alexei%20Gruverman.html) He then held research scientist positions in Japan, at the Joint Research Center for Atom Technology in Tsukuba and at Sony Corporation in Yokohama.[8](https://2022.ieee-isaf.org/presenter/alexei-gruverman/) While working in Japan he pioneered an SPM-based method for non-destructive, high-resolution imaging of ferroelectric domains in thin films and memory devices, the approach now known as Piezoresponse Force Microscopy.[4](https://www.sfu.ca/isaf2011/Alexei%20Gruverman.html)
## Career
After Japan, Gruverman held a research professorship at [North Carolina State University](https://www.edgepedia.org/north-carolina-state-university) before joining UNL in 2007.[8](https://2022.ieee-isaf.org/presenter/alexei-gruverman/) • [9](https://mse.rpi.edu/seminars/2021/nanoelectronic-phenomena-low-dimensional-ferroelectrics) According to his RPI seminar biography, at UNL he served as a theme leader of the Semiconductor Research Corporation-sponsored Center for Nanoferroic Devices.[9](https://mse.rpi.edu/seminars/2021/nanoelectronic-phenomena-low-dimensional-ferroelectrics) A 2022 conference biography describes him as a Charles Bessey Professor;[8](https://2022.ieee-isaf.org/presenter/alexei-gruverman/) the current UNL directory and recent university news list him as Charles J. Mach University Professor of Physics.[1](https://directory.unl.edu/people/agruverman2) • [10](https://news.unl.edu/article/nebraska-physicist-global-team-put-new-spin-on-energy-saving-tech)
## Piezoresponse force microscopy
PFM images ferroelectric domains by detecting the local mechanical deformation a material produces under an applied voltage, allowing domain structures in thin films and memory devices to be mapped without destroying them.[4](https://www.sfu.ca/isaf2011/Alexei%20Gruverman.html) Since its inception more than 25 years ago, PFM has become one of the mainstream techniques in nanoferroic materials research, and its evolution from an imaging method into a set of advanced techniques has helped launch areas such as multiferroic devices and domain wall nanoelectronics.[11](https://pmc.ncbi.nlm.nih.gov/articles/PMC6458164/)
A major application in Gruverman's group is switching kinetics in ferroelectric capacitors, the core elements of ferroelectric random access memory (FRAM), a non-volatile memory technology with high reading and writing speed, low power consumption, high endurance, and scalability.[12](https://gruverman.unl.edu/research/switching-behavior-and-scaling-effects-ferroelectric-structures/) Using PFM, the group obtains snapshots of instant domain configurations during very fast polarization reversal, below 100 nanoseconds, showing how quickly different parts of a capacitor respond to the driving voltage.[12](https://gruverman.unl.edu/research/switching-behavior-and-scaling-effects-ferroelectric-structures/)
## Representative work
**Mechanical writing of ferroelectric polarization** (Science, 2012) demonstrated that the stress gradient generated by the tip of an atomic force microscope can mechanically switch the polarization in the nanoscale volume of a ferroelectric film.[5](https://www.science.org/doi/10.1126/science.1218693) The films used were single-crystalline barium titanate with a vertically aligned dipole moment created by compressive stresses.[5](https://www.science.org/doi/10.1126/science.1218693) Nebraska MRSEC describes the result as the first experimental observation of mechanically induced reversal of ferroelectric polarization: the tip-induced pressure creates a stress gradient that affects the polarization like an electric field, and because the tip pressure is highly localized, domains as small as several nanometers can be written, allowing extremely high-density data storage on the order of terabits per square inch.[13](https://mrsec.unl.edu/program-highlights-writing-polarization/) Because switching is voltage-free, it avoids charge injection, dielectric breakdown, and leakage current problems, a direction relevant to low-energy nanoelectronics.[13](https://mrsec.unl.edu/program-highlights-writing-polarization/) The paper is available at [DOI 10.1126/science.1218693](https://doi.org/10.1126/science.1218693).[5](https://www.science.org/doi/10.1126/science.1218693)
## Honors and recognition
Gruverman's awards include the Ikeda Foundation Award (2004) and the ISIF Outstanding Achievement Award (2010).[4](https://www.sfu.ca/isaf2011/Alexei%20Gruverman.html) In 2014 he was elected a Fellow of the [American Physical Society](https://www.edgepedia.org/american-physical-society) for his pioneering contribution to the development of piezoresponse force microscopy.[7](https://events.uvm.edu/event/physics-colloquium-with-dr-alexei-gruverman) He was elected an International Fellow of the Japan Society of Applied Physics in 2016, received the IEEE Ferroelectrics Recognition Award in 2017, the Humboldt Research Award in 2020, and the [Lars Onsager](https://www.edgepedia.org/lars-onsager) medal in 2024.[7](https://events.uvm.edu/event/physics-colloquium-with-dr-alexei-gruverman)
## Recent work
In a perspective published in [Nature Materials](https://www.edgepedia.org/nature-materials), an international team including Gruverman reports that the traditional hallmarks of antiferroelectrics no longer capture the full range of materials showing similar behavior. Gruverman stated that the classical definition of [antiferroelectricity](https://www.edgepedia.org/antiferroelectricity), a cornerstone of the field for decades, no longer captures the full complexity of emerging modern materials; the rethinking could support faster-charging electronics, smarter power grids, and energy-saving cooling technologies.[10](https://news.unl.edu/article/nebraska-physicist-global-team-put-new-spin-on-energy-saving-tech)
