Welcome! To the
David
Blyth web site. In these few pages I will
give a very basic explanation of semiconductor physics and then an outline
of my work at Essex. I will also provide some information about myself
and some of my other interests and achievements.
I am a Phd student
studying under the supervision of Dr Naci Balkan in the photonics group
working within the Electronic systems engineering department at Essex University.
My main area of research is that of Hot electrons in Gallium Nitride, these
hot electrons are introduced into the samples by utilising the piezoelectric
qualities of the material to set up acoustic wavefronts. A laser beam with
photon energies less than the bandgap of the sample is then directed onto
the sample and the photons interact with the wavefronts and either gain
or lose energy. The change in energy of the photons will either decrease
or increase their wavelengths and also alters the intensity and direction
of the optical beam. This type of control makes possible a large number
of applications involving the transmission, display, and processing of
information.
