Ensemble Monte Carlo study of a novel heterojunction real-space transfer logic transistor (RSTLT)

Abstract

A novel real-space transfer logic transistor (RSTLT) is proposed based on the real-space transfer of hot electrons in a four-terminal heterojunction microstructure. Self-consistent steady-state and transient Monte Carlo simulations demonstrate that the RSTLT features both logic flexibility and ultra-fast switching speed. Calculated results show that the proposed RSTLT realizes NOT and EQUIVALENT logic functions in a single heterojunction device, and a conservative estimate of the characteristic switching time is approximately 3 psec.<>
