Ferroelectric Gate on AlGaN/GaN Heterostructures

Paul Muralt, Nava Setter, Igor Stolichnov, Lisa Malin

A PZT, Pb(Zr,Ti)O-3 (40:60), ferroelectric layer has been successfully deposited onto a Al0.3Ga0.7N/GaN heterostructure with a 2DEG, two dimensional electron gas. Due to the chemical and temperature stability of AlGaN/GaN it was possible to implement the c ...

Ferroelectric gate for control of transport properties of two-dimensional electron gas at AlGaN/GaN heterostructures

Paul Muralt, Nava Setter, Igor Stolichnov, Lisa Malin

The concept of a field-effect transistor with ferroelectric gate has been implemented using the GaN/AlGaN heterostructure combined with Pb(Zr,Ti)O-3 ferroelectric layer. The processing conditions were optimized in a way to obtain textured Pb(Zr,Ti)O-3 film ...

Ferroelectric gates with rewritable domain nanopatterns for modulation of transport properties in GaN/AlGaN heterostructures

Jean-François Carlin, Nava Setter, Enrico Colla, Igor Stolichnov, Lisa Malin

The concept of field-effect transistor with ferroelectric gate in combination with the advanced technique of direct domain writing is applied for modulation of transport properties of 2D electron gas located close to the interface in a GaN/AlGaN heterostru ...

Microscopic aspects of the region-by-region polarization reversal kinetics of polycrystalline ferroelectric Pb(Zr,Ti)O-3 films

Nava Setter, Alexander Tagantsev, Enrico Colla, Igor Stolichnov, Lisa Malin

The region-by-region polarization switching in ferroelectric Pb(Zr,Ti)O-3 thin films sandwiched between Pt electrodes has been directly observed using piezoelectric scanning probe microscopy. A resolution improved by one order-of-magnitude compared to the ...
