減少奈米線的寬度可以增加表面對體積的比,可以增加表面電荷的導電率的靈敏度,本文研究不同的α-Si/SiGe寬度對α-Si/SiGe core/shell奈米線的影響 Reducing the width of a nano-wire increases its surface to volume ratio, increasing the sensitivity of its conductivity to charges on its surface. Our previous studies have shown that increasing the Ge fraction in Si1-xGex nano-wires improves their sensit
