This book presents the latest developments in semiconducting materials and devices providing
up-to-date information on the science processes and applications in the field. A wide range
of topics are covered including optoelectronic devices metal-semiconductor junctions
heterojunctions MISFETs LEDs semiconductor lasers photodiodes switching diodes tunnel
diodes Gunn diodes solar cells varactor diodes IMPATT diodes and advanced semiconductors.
Detailed attention is paid to advanced and futuristic materials. In addition clear
explanations are provided of for example electron theories high-field effects the Hall
effect transit-time effects drift and diffusion breakdown mechanisms equilibrium and
transient conditions switching and biasing. The book is designed to meet the needs of
undergraduate engineering students and will also be very useful for postgraduate students it
will assist in preparation for examinations at colleges and universities and for other
examinations in engineering. Practice questions are therefore presented in both essay and
multiple choice format and many solved examples and unsolved problems are included.
