用正电子湮没多普勒增宽谱测量金属中电子的费米能级

THE MEASUREMENT OF FERMI ENERGY LEVEL OF ELECTRON IN METAL BY POSITRON ANNIHILATION DOPPLER BROADENING SPECTROMETER

高校中不少实验室具有半导体探头能谱仪，可扩展用作正电子湮没多普勒增宽谱仪。

A student experiment of solid state physics is designed by positron annihilation Doppler broadening spectrometer. The Fermi energy level of electron in metal can be measured.\;
