“…They are expected to play important roles as functional components in future nanoscale field effect transistors [1], high efficiency photo detectors [2,3], light emitting diodes [4], photovoltaic cells [5], medicine sensors [6], phonon devices [7][8][9][10], etc. Among the family of III-V semiconductors, bulk InSb has the smallest direct band-gap (0.17 eV), the highest electron mobility (≈ 7.7 × 10 4 cm 2 /Vs) in part due to the small electron mass (0.015m e ).…”
