A hafnium oxide ferroelectric is a thin film of doped HfO₂ with switchable polarization, first reported in 2011 and a leading candidate for ferroelectric memory.
Hafnium oxide ferroelectricity
Hafnium oxide ferroelectricity is the switchable spontaneous polarization in hafnium dioxide thin films, unexpectedly discovered in silicon-doped HfO2 in 2011 and compatible with standard CMOS chipmaking.
Hafnium pentatelluride
Hafnium pentatelluride (HfTe5) is a layered compound of hafnium and tellurium, studied first as a thermoelectric material and since 2014 as a topological quantum material.
Hafnium silicate
Hafnium silicate is a mixed oxide of hafnium and silicon used as a high-k gate insulator in silicon transistors, first mass-produced at Intel's 45 nm node in 2007.
Hafnium zirconium oxide
Hafnium zirconium oxide (HZO), most commonly the equimolar solid solution Hf0.5Zr0.5O2, is a ferroelectric oxide used as the active layer in emerging non-volatile memories and ferroelectric transistors, deposited by atomic layer deposition.
Hafnium(IV) oxide
Hafnium(IV) oxide, also known as hafnia (HfO₂), is a white, chemically stable oxide of hafnium. It replaced silicon dioxide as the gate insulator in Intel's 45 nm chips in 2007 and underlies ferroelectric memory.
