Abstract

AbstractWe studied the thermoelectric and electrical properties of InSb thin films prepared by metalorganic chemical vapor deposition. The thermoelectric properties were evaluated using power factor (Pf =α2/Ï), which is an important criterion, and a value of 10-3 W/mK2 is a standard for practical use. Maximum value of Pf was 2.4×10-3W/mK2 at 600K for 1-μm-thick InSb, 3.4×10-3W/mK2 at 600K for 3-μm-thick InSb, and 5.8×10-3W/mK2 at 600K for 5-μm-thick InSb. On the other hand, the maximum Pf of bulk-InSb was 5.4×10-3W/mK2 at 600K.
