Summary

There is growing evidence for an enhancement of the thermoelectric figure of merit ZT in low dimensional structures. Thermoelectric nanostructures based on such materials could have a series of applications in sensors, coolers and low power energy conversion systems. Basic thermoelectric properties of Pb1–xSrx(Se,Te) epitaxial films grown by molecular beam epitaxy (MBE) on BaF2 (111) substrates are presented. The structural quality is studied by high resolution X-ray diffraction (XRD). For multi quantum well (MQW) films XRD and atomic force microscopy (AFM) analysis show high structural perfection. Measurements of transport properties indicate an enhancement of the 2D-power factor σS2. High quality Bi2Te3-layers can also be prepared on BaF2 (111) substrates using MBE. Multiple stacks of epitaxial IV-VI/V-VI layers are made. Growth characteristics were analyzed by RHEED, AFM, SEM and SIMS.
