SEMICONDUCTOR MATERIALS

The future materials problems should see increased efforts on techniques for tailor-making semiconductors for certain desir prop r ies. Mixi g of miscible compounds appears promising in this respect. Epit xi l vapor grow h techniques also warrant further exploitation. Other approaches for specific applications are expected to be emphasized, such as mixed valency semiconductors for high temp rature thermoelectric elements. Theoretical a vances are expected in terms of nergy band structure based on cyclotron resonance and related measurements. Investiga ions will continue to be based on the role of imp rf ctions i e icon uctor uthor
