The aim of this course is to introduce to the stude
nts to the fundamentals of the optoelectronic
properties of semiconductor materials and a wide
variety of modern optoelectronic devices. These i
nclude pn junctions, pho
To understand the optical properties of a device it
is important that we investigate how light interact
with the material.
When light shines onto the active region of a
device it may be absorbed, reflected or
Introductory Quantum Mechanics
The Quantum Concept: Blackbody Radiation
A solid object gives off light when heated.
In fact solid objects in equilibrium with the surroundings
emit a spectrum of radiation characteristic of
Solar cells constitute a critical technology for
overcoming global environmental and energy
To date 95% of solar cells are Si based.
The energy output from the sun covers the
spectral range 0.2
Energy Band Theory
Electrons moving in a semiconductor crystal are particles
in a 3-D box with a very complicated interior.
In a real crystal at operational temperature there will be
lattice defects and the semiconductor
