Solid-State Electronics I

This course aims to provide an introduction to the electrical properties of materials, in particular crystalline
semiconductors, and then to use this foundation to develop a basic understanding of the physical operating
principles of the common electronic devices. The topics covered include:Basic definitions of metal, insulator
and semiconductor based on existence of energy bands in crystalline material. Classification of semiconductor
materials.Charge transport in metals and pure/doped semiconductors. Equilibrium and nonequilibrium conditions.
Continuity and Poisson equations.Principles of semiconductor processing. Moore's Law. Semiconductor business
aspects. Ideal PN junction. Electrostatic behaviour of depletion layer. Physical explanation and derivation of
static current-voltage characteristic. Non-ideal behaviour.Concept of small-signal and large-signal device
model. Junction FET. Structure, operating structure, operating principles, characteristics, applications.
Static analysis for pinch-off and drain current; small-signal and large-signal models.The Metal-Semiconductor
Field-Effect Transistor (MOSFET): The MOS capacitor,formation of inversion layer; the enhancement type MOSFET:
structure, operatingprinciples, characteristics, applications; DC analysis for threshold and static
draincurrent; small-signal and elementary large-signal models; CMOS inverter and basic CMOS logic functions.
The Bipolar Junction Transistor (BJT): structure of NPN and PNP bipolars, operating principles,
characteristics, applications; biasing configurations, cut-off and saturation, current-gains;
design trade-offs; small-signal and large-signal models.
