  II-VI Semiconductor Quantum Dot for Visible Emission Applications

                    Professor Martin Munoz
  Physics Department, Virginia Commonwealth University, Richmond, VA

In recent years there has been increasing effort in the development of
semiconductor quantum dots (QDs). Technological applications such as the
stimulated emission of QD-structures, high intensity displays, and the
possibility of QD-laser with ultra low threshold motivate this trend.
The tuning of the emission of QD structures makes possible to produce light of
specific wavelengths within certain limits, these limits are determined by the
QD and barrier properties. Wavelengths for optical communications and for
visible applications are of huge interest for many practical reasons. In the
case of visible applications, it is highly desired to have a QD system that
allows an easy control of the main wavelengths visible spectrum (red, green
and blue).

In this talk, I will present the fundamentals of the growth and
characterization of CdSe/ZnCdMgSe QDs structures and their potential use for
light sources in entire visible spectrum, full color displays and white
sources.
