ABSTRACT: The
variational effective mass with respect to the e-p coupling constant for
different values of cutoff wave vector is performed in quantum dot. The self-trapping
transition of acoustic polaron in quantum dot is reconsidered by character of
the effective mass curve varying with the e-p coupling. The holes are determined
to be self-trapped in AlN quantum dot systems.
