Title :永久磁石を用いた半導体2次元電子系のホール測定
Authors :鈴木 恭一
Issue Date :Dec-2018
Abstract :Hall measurement is useful to investigate basic electronic properties of semiconductor wafers. Since the invention of the strong permanent magnets, Hall measurement systems using permanent magnets have been commercially available. However, these systems include too many functions and therefore are too expensive for single laboratory use. We propose here a very simple Hall measurement system with a neodymium permanent magnet at low cost. Using this system, electron density and mobility in a Si-doped AlGaAs/GaAs single heterostructure were measured. Obtained results are comparable to those found by using the commercially available system.
