Ultrathin Membranes and 3D Nanoarchitectures of Hollow Tetrapodal Structures based on GaN and β-Ga2O3 for Multifunctional Applications

Abstract

We report on development of large-sized ultrathin GaN single crystalline membranes and of 3D nanoarchitectures based on GaN hollow microtetrapods with nanoscopic thin walls. It is shown that memristive networks consisting of GaN ultrathin membranes exhibit learning mechanisms such as habituation and dishabituation followed by storage of the response to a certain electrical stimulus, while the 3D nanoarchitecture based on GaN hollow microtetrapods (called aero-GaN) represents the first artificial material exhibiting dual hydrophobic-hydrophilic behaviour.
