Study of the Electron-Focusing Spectrum by Quantum Theory and by the Quantized Billiard Model
The wave functions of electrons in the electron focusing geometry are quantum-mechanically calculated. The transmission probability from the emitter to the collector, which is considered to be proportional to the electron focusing spectrum (EFS), is discussed. An effective classical model is introduced in order to investigate the intrinsic nature of EFS. It is found that the reproducible substructure in experimental EFS is attributed to the diffraction of higher mode components in the incident wave.
