About this book Introduction 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.

B to C B to C During this time interval the electric field is sufficiently large for the avalanche to continue, and a dense plasma of electrons and holes are created.

The voltage decreases to point D. A long time is required to remove the plasma because the total plasma charge is large compared to the charge per unit time in the external current.

At point E the plasma is removed, but a residual charge of electrons remains in one end of the depletion layer and a residual charge of holes in the other end.

As the residual charge is removed, the voltage increases E to F. At F, all the charge that was generated internally has been removed.

From point F to G, the diode charges up again like a fixed capacitor. At G, the diode current goes to zero for half a period and the voltage remains constant at VA until the current comes back on and the cycle repeats The electric field expression Thus the time t at which the electric field reaches Em at a given distance x into the depletion region is Differentiating w r t time t - nominal transit time of the diode in the high field.

Therefore the TRAPATT mode is still a transit-time mode That is the time delay of carriers in transit time between injection and collection is utilized to obtain a current phase shift favorable for oscillation.

BARITT DIODES Introduction Barrier injected transit time diodes Long drift regions The carriers traversing the drift regions are generated by minority carrier injection from forward biased junctions instead of being extracted from the plasma of an avalanche region P-n-p, p-n-v-p, p-n-metal and metal-n-metal For a p-n-v-p baritt diode the forward biased p-n junction emits holes into the v region. These holes drift with saturation velocity through the v region and are collected at the p contact.

Narrow Bandwidth and power outputs limited to a few milliwatts. There are also very many new LED developments that are changing the way displays can be used and manufactured.

It is found that when light strikes a PN junction it can create electrons and holes. Typically photo-diodes are operated under reverse bias conditions where even small amounts of current flow resulting from the light can be easily detected.

Photo-diodes can also be used to generate electricity. For some applications, PIN diodes work very well as photo detectors.

It has the standard P type and N-type areas, but between them there is an area of Intrinsic semiconductor which has no doping. The area of the intrinsic semiconductor has the effect of increasing the area of the depletion region which can be useful for switching applications as well as for use in photodiodes, etc.

At low currents the drop may be somewhere between 0. To achieve this performance they are constructed in a different way to normal diodes having a metal to semiconductor contact.

They are widely used as clamping diodes, in RF applications, and also for rectifier applications. Schottky diodes: This type of diode has a lower forward voltage drop than ordinary silicon PN junction diodes.

These diodes rely on a very fast turn off characteristic of the diode for their operation. The diode has a reverse bias placed upon it and this varies the width of the depletion layer according to the voltage placed across the diode.

In this configuration the varactor or varicap diode acts like a capacitor with the depletion region being the insulating dielectric and the capacitor plates formed by the extent of the conduction regions.
