On the use of bismuth in quantum wells

A rapid survey of some theoretical considerations concerning the use of multiple quantum well structures (MQWS) in thermoelectricity is given as well as why bismuth can be a prospective material for the development of a new class of thermoelectric systems. Problems arising from Bi film synthesis are discussed, in relation with the preparation of Bi-based MQWS. Some experimental results are reported on pulsed laser deposited Bi films prepared in our laboratory.
