Abstract:
Energy spectrum of indium antimonide (InSb) quantum dots (QD) was analyzed in this paper. Properties of energy spectrum levels were determined both by calculations and experiments using differential tunneling current-voltage characteristics (CVC) rated to static conductivity. It was confirmed that relatively large QD (size of about 20 – 25 nm) exhibit quantum size effects. Critical values of the characteristic parameters of InSb QD are analyzed, in which application of the differential tunneling current-voltage characteristics method for express analysis of the characteristic sizes of QD leads to significant errors (more than 10 %).
Keywords:
