大的激子结合能有什么好处？
The title says it all. I'm doing a presentation on
ZnOnanoflowers
, and one article says that the
bandgap
of 3.3eV in combination with the high
exciton
binding energy of 60meV makes
ZnOpromising for optoelectronic applications. The
bandgap
I understand, what property does the
exciton
binding energy translate to?
Roughly speaking the
exciton
binding energy gives the stability against thermal dissociation of
excitons
.Theat
means that there will still be a significant number of  ...
