3.5.2,载流子的迁移率图7表示我们用分子束外延技术生长的外延层材料在77K时的电子迁移率与组分的关系,组分对应的波段范围从中波红外一直到超长波红外。长波红外(X=0.23)材料的典型迁移率是大于1×10~5cm~2/V.S。图中的实心线是为了帮助眼睛看清楚而画出来的,它表明迁移率随组
3.5.2 Carrier mobility Figure 7 shows the electron mobility of the epitaxial layer grown by molecular beam epitaxy at 77K as a function of composition. The corresponding band ranges from medium-wave infrared to ultra-long wave Infrared. The typical mobility of long wave infrared (X = 0.23) material is greater than 1 × 10 ~ 5cm ~ 2 / V.S. The solid line in the figure is drawn to help the eyes see clearly, indicating that the mobility varies with group
