Semiconductors

Course contents

• Band model of semiconductor
• Effective-mass concept
• Fermi-energy position
• Modification of free electron model to describe resistivity
• P-n junction
• Mechanisms for current flow
• Structures and operation of transistors
• LEDs, solar cells, and laser diodes

Learning outcomes

At the end of the course the student will be able to

• localise those electron levels from a spectrum, which determine the resistivity of a semiconductor
• explain principles of following measurement methods: photoelectron spectroscopy and low energy-electron diffraction
• explain how transistor, LED, and solar cell work
• localise those parts of transistor, LED, and solar cell, which determine device performance (e.g., energy efficiency and electricity-to-light transformation).

The following skills developed during the course are useful concerning the working life:

• critical thinking
• connecting material properties/issues to operation of practical devices of electronics and photonics.
