Evidence of p/n homojunction formation in Zn/sub 3/P/sub 2/
Heating of magnesium/p-Zn/sub 3/P/sub 2/ contacts at 100 /sup 0/C results in a approx. 10/sup 2/ lower reverse saturation current than found for the unheated metal-semiconductor diode. Spectral response and electron-beam-induced current (EBIC) measurements show the formation of a buried junction upon heating, and the latter method has been used to obtain values of junction depth and minority carrier diffusion length. A model expressing the collection efficiency of an n-on-p homojunction shows good agreement with experiment when the minority carrier diffusion lengths and junction depth determined by EBIC measurements are used. This is the first evidence that p/n homojunctions may be formed in Zn/sub 3/P/sub 2/.
