FinFET原子层通道数据集

本项目设计了高200-300 nm的硅晶体台阶模板，采用湿法喷涂化学气相沉积（CVD）技术，实现了在模板台阶侧壁上共形生长过渡族金属硫化物单原子层晶体（单层MoS2、WS2等）。通过采用多重刻蚀等微纳加工工艺，制备出具有单层极限的二维半导体材料沟道的鳍式场效应晶体管。通过探针台表征其电学特性，并使用COMSOL模拟该器件理想状态下的电学特性。This project designed a silicon crystal step template with a height of 200–300 nm. Wet-spray chemical vapor deposition (CVD) was utilized to achieve conformal growth of transition metal dichalcogenide monolayer crystals (such as monolayer MoS₂, WS₂) on the sidewalls of the template steps. Via micro-nano fabrication processes including multiple etching, fin field-effect transistors (FinFETs) with channels made of two-dimensional (2D) semiconductor materials at the monolayer thickness limit were fabricated. The electrical properties of the fabricated devices were characterized using a probe station, and their ideal-state electrical characteristics were simulated via COMSOL.
