摘要

The literature was surveyed to determine potential applications of acoustic and plasma phenomena in superlattices. The use of folded zone acoustic phonons and acoustic surface plasmons in III-V compounds, such as AlGaAs/GaAs superlattices is addressed. A dielectric phonon filter is presented and an acoustic resonator is considered. Surface plasmons and surface acoustic plasmons are discussed, and a transducer, delay line, and mixer are proposed as applications. A 500-GHz isolator utilizing surface magnetoplasmons is also presented.
