Resonant excitation of coupled space charge acoustic waves in thin n-GaAs film is theoretically investigated. Possible mechanisms of electroacoustic coupling are piezoeffect and deformation potential. The film is placed onto a substrate i-GaAs without an acoustic contact. The film includes two-dimensional electron gas with a high negative differential(More)
Silicic calderas form during explosive volcanic eruptions when magma withdrawal triggers collapse along bounding faults. The nature of specific interactions between magmatism and tectonism in caldera-forming systems is, however, unclear. Regional stress patterns may control the location and geometry of magma reservoirs, which in turn may control the spatial(More)
Resistive-switching devices based on Metal–Insulator–Metal (MIM) structures have shown promising memory performance characteristics while enabling higher density of integration. Usually, these MIM devices are fabricated using different processing conditions including high temperature thermal treatments that could lead to undesirable chemical reactions in(More)
