Modern device electronics: semiconductor fundamentals including crystals and energy bands, charge carriers (electrons and holes), doping, and transport, (drift and diffusion); unipolar devices with the MOS field effect transistor as a logic device and circuit considerations; basic concepts of generation-recombination and the P-N junction as capacitors and current rectifier with applications in photonics; bipolar transistors as amplifiers and switching three-terminal devices. Course Information: Prerequisite: ECE 210; PHYS 214; credit or concurrent registration in ECE 329.

Microelectronics and Photonics

The purpose of this course is to provide the student with the essential background on semiconductor materials and a basic understanding of the following semiconductor electronic devices that will be required for a successful career in electrical engineering:

p-n Junctions

Light-Emitting Diodes/Photodetectors

Bipolar Junction Transistors

Field Effect Transistors

These topics are important to the professional electrical or computer engineer because these devices are utilized in almost every area of electrical or computer engineering. To be productive and remain employed throughout a 40+ year career in electrical or computer engineering, the electrical and computer engineer needs to understand the fundamentals of semiconductors and the operation and limitations of these devices. A successful engineer will be able to apply this knowledge in the different areas of electrical engineering, whether he or she works directly in circuits and system design, control systems, communications, computers, electromagnetic fields, bioengineering, power systems, directly in the semiconductor industry, or in areas yet to develop that will certainly rely heavily on semiconductor devices and/or integrated circuits.

The material in this course will provide the background that will give the student the ability to learn and understand the performance and limits of improved devices that will be required throughout your electrical or computer engineering career.

If students have not already acquired the ability to write simple computer programs and produce computer generated graphs using Mathematica, Excel, Matlab, MathCAD, or some other program, this ability should be acquired in the first four weeks of the course.

Weekly homework are __assigned on Friday__ and are turned in __at the beginning __of the next Friday class, unless otherwise specified.

This course is required for both electrical engineering and computer engineering majors. The goals are to give the students an understanding of the elements of semiconductor physics and principles of semiconductor devices that (a) constitute the foundation required for an electrical engineering major to take follow-on courses, and (b) represent the essential basic knowledge of the operation and limitations of the three primary electronic devices, 1) p-n junctions, 2) bipolar transistors, and 3) field effect transistors, that either an electrical engineer or a computer engineer will find useful in maintaining currency with new developments in semiconductor devices and integrated circuits in an extended career in either field.

**By the time of exam No. 1 (after 17 lectures), the students should be able to do the following:**
