摘要:

N‐doped vertical AlGaAs quantum wells have been fabricated by metalorganic vapor phase epitaxial growth of a single‐doped AlGaAs layer on a submicron grating. Intersubband absorption at normal incidence is demonstrated in those quantum wells. This opens new possibilities for infrared quantum well devices using intersubband transitions. ©1995 American Institute of Physics.
