MATS8AB

Properties of semiconductors

ECTS Credits : 2

Duration : 21 hours

Semester : S8

Person(s) in charge:

Christophe CANDOLFI, Associate Professor, christophe.candolfi@mines-nancy.univ-lorraine.fr 

Keywords:

semiconductors, doping, diode, transistor, optical properties

Prerequisites: 

Electrical and thermal properties of materials, Quantum mechanics, Statistical physics

General objective :

Understand the underlying physics of semiconductors and the fundamentals of semiconductor devices (diode, transistor, light emitting diode, laser diode, solar cell)

Program and Contents:


Semiconductors are ubiquitous in our everyday life and are at the root of our information technology. Controlling their electrical properties through doping enables combining these materials to obtain electronic devices found in integrated circuits. Their peculiar properties, halfway between metals and insulators, drive these materials as materials of choice for emitting or detecting electromagnetic waves.

The purpose of this course is to understand how the transport properties of semiconductors can be tuned by impurity atoms and to learn the fundamentals of semiconductor devices such as diodes, transistor and optoelectronic devices (LED, laser diode and solar cell).
