ZnO is a II-VI compound semiconductor with a bandgap energy of 3.4 eV.
It is a potential material since it has advantages, large exciton binding energy
of 60 meV, transparent in visible region, easy to obtain n-type conductivity, an abundant and
none-toxic material. We are investigating ZnO films and nanoparticles for the
applications of high efficiency UV light emitters (LEDs for solid sate
lightning, UV LDs), devices using transparent conductive films and nano-bio,
nano-medical applications.
