In this paper, the spectral element method is used to build a hydrodynamic model in order to solve the semiconductor transient simulation. The hydrodynamic model consists of five nonlinear differential equations: the electron current continuity equation and hole current continuity equation, electron energy-balance equation, hole energy-balance equation and Poisson's equation. Unlike the drift-diffusion(DD)...
We report on 2D numerical simulations of photoresponse characteristic for mid-wavelength InSb infrared photodiodes. Effects of thickness of absorption layer on the photoresponse have been investigated for both front-side and back-side illuminated devices. Optimal thickness of absorption layers for different diffusion lengths are extracted theoretically. An empirical formula is proposed to predict...
Based on the new finding on switching behavior, for the first time a new memory operation principle is proposed to control the switching and to achieve improved performance of oxide-based RRAM including device-to-device and cycle-to-cycle uniformity, RESET current, and window of RHRS/RLRS ratio. Furthermore, a numerical simulation method is developed to evaluate the validity of the new operation principle...
