An observation of central cell structure in magneto-impurity resonances in n-type InP

open access: yesJournal of Physics C: Solid State Physics, 1978
Magneto-impurity resonances have been observed in all components of the magnetoresistance tensor of n-type InP at 20K, and in the warm electron coefficient beta determined by third harmonic measurements. The extrema show central cell structure similar to that found in the electronic transitions between shallow donor states, which can be observed by ...
