The capability of scanning electron acoustic microscopy in semiconduct
or materials has been studied. The signal generation mechanisms and ap
plications of scanning electron acoustic microscopy in n-GaSb (Te-dope
d) crystals, and GaInAsSb on GaSb, GaSb on GaAs and InSb epilayer on a
GaAs substrate are investigated, which shows the new technique for im
age and characterization of thermal elastic and pyroelectric property
variations on a microscale resolution. Copyright (C) 1996 Elsevier Sci
