WebThe electrode-limited conduction mechanisms include Schottky or thermionic emission Fowler-Nordheim tunneling, direct tunneling, ... The energy barrier height at the metal-dielectric interface may be lowered by the image force. The barrier-lowering effect due to the image force is called Schottky effect. Web29 jan. 2024 · A new analysis method of reverse leakage current for β-Ga 2 O 3 Schottky barrier diodes is performed by using two models: bias dependence and no bias dependence of barrier height. The method incorporates both the current induced by the tunneling of carriers through the Schottky barrier and the current induced by the thermionic emission …
WebGaN Schottky barrier ultraviolet photodetectors with unintentionally doped GaN and lightly Si-doped n−-GaN absorption layers were successfully fabricated, respectively. The high-quality GaN films on the Si substrate both have a fairly low dislocation density and point defect concentration. More importantly, the effect of Si doping on the performance of the … Web19 jul. 2011 · This result clearly supports that tunneling has a significant role at the forward current and thermionic-field emission (TFE) process is the main mechanism in Au/ZnO nanowire Schottky diode. Although the image force lowering (ΔФ B), ascribed for enhanced electric field at the depletion region due to small size of the nano-Schottky …
