Resonant interband tunneling through multiple subbands in an InAs/AlSb/GaSb interband tunneling structure

The magnetotunneling characteristics of a p-type well InAs/AlSb/GaSb resonant interband tunneling structure are investigated. Experimental results indicate that tunneling occurs through multiple subbands, including both light-hole and heavy-hole like subbands. The data can be used to plot out critical points on the GaSb subband structure.
