Abstract
This chapter considers the interaction of phonons with one- and zero-dimensional (1-D and 0-D) carrier systems in quantum wires and dots. Wires and dots are discussed in separate sections: each starting with a brief review of how the structures are formed, and then going on to consider their basic physical properties. The theory of emission and absorption of bulk (3-D) phonons by electrons in 1-D and 0-D is considered. The chapter explains how the requirements of energy and momentum conservation leads to the ‘phonon bottleneck’, i.e. a reduction in the carrier-phonon scattering rates as the dimensionality is reduced. Each section ends with a review of experimental measurements of carrier-phonon interactions. The focus is on phonon measurements using the techniques of heat pulses and phonoconductivity. The chapter concludes with a discussion of the outstanding issues, e.g. the carrier relaxation processes in quantum dots.
