Oxygen vacancy driven resistive switching in SrTiO3/Si(001) heterostructures due to an electronic mechanism
Resistive switching (RS) has been extensively studied for its potential applications in non-volatile memory and neuromorphic devices. RS in oxides is closely linked to the presence of oxygen vacancies...
Time-resolved electron temperature oscillations in Hall thrusters
Hall thruster discharge dynamics are complex and are largely influenced by the time-dependent behavior of electrons in the thruster channel. FastOES, a novel non-invasive diagnostic, enables time-reso...
