Optical Properties of Tetrahedrally Bonded Amorphous Semiconductors: Absorption Spectra and Absorption Edge,y. In contrast to glasses, which will be treated in other lectures, these materials can only be obtained in the amorphous state as thin films, which can be prepared by evaporation, sputtering, electrochemical deposition, glow-discharge decomposition, etc.

Paul Cull,Mary Flahive,Robby Robsonf-chip SAW (surface acoustic wave) filters, due to its property of high-Q filtering over a wide RF (radiofrequency) range. This chapter discusses the design of two SAW-less RF front-ends for TDD (time-division duplexing) and FDD (frequency division duplexing). The first is an area-efficient SAW-less
