Triggering times of Gunn diodes
Electronics Letters, 1969 Based on the operating-point trajectory theory, the build-up/ quenching time of triggered Gunn domains is examined by means of a digital computer. A simple relation is given between the amplitude and time of the trigger pulse.

Nucleation and Propagation of Traveling Charge Domains in a Planar AlGaN/GaN Triode Structure
physica status solidi (a), Volume 222, Issue 23, December 2025.This work presents a novel model for the nucleation of charge domain instabilities in semiconductors exhibiting negative differential drift velocity, identifying diffusion as the key factor inhibiting domain formation. A planar Gunn triode structure is proposed which overcomes obstacles to the realization of GaN‐based Gunn effect devices with ...

Observation of negative differential conductance in a reverse-biased Ni/Ge Schottky diode
, 2009 We report the experimental observation of negative differential conductance in a Ni/Ge Schottky diode. With the aid of theoretical models and numerical simulation we show that, at reverse bias, electons tunnel into the high electric field of the ...

Exploring Double NDR Modulation and UV‐NIR Photodetection in MoS2/Sb2Se3 Heterostructures
Advanced Optical Materials, Volume 13, Issue 32, November 14, 2025.In this study, a van der Waals Sb2Se3/MoS2 heterostructure exhibits dual negative differential resistance (NDR) peaks at room temperature. The first originates from band‐to‐band tunneling, while the second, triggered under laser illumination, is attributed to trap states and recombination dynamics.
