EENG 200 Introduction to Electronics

This introductory course has no pre-requisites beyond high school calculus and is designed to help students to:

  • Understand DC and AC characteristics of basic electric circuits, including both passive and active varieties, as building blocks of analog systems
  • Understand the basic concepts of some semiconductor devices (diodes, bipolar junction transistors, MOSFETs, op amps) for analog and digital applications
  • Analyze, design, build, and test moderately sophisticated electronic circuits
  • Be able to take more advanced electronic circuits-related courses with minimum difficulty.

EENG 406 / ENAS 806 Photovoltaic Energy

Electricity from photovoltaic solar cells is receiving increasing attention due to growing world demand for clean power sources. This course primarily emphasizes: device physics of photovoltaics, statistics of charge carriers in and out of equilibrium, design of solar cells, and optical, electrical, and structural properties of semiconductors relevant to photovoltaics. Two laboratory sessions and a final project will aid students in understanding both the applications and limitations of photovoltaic technology. The main objectives of this course are:

  • To equip students with the necessary background and analytical skills to understand and assess established and emerging photovoltaic technologies
  • To familiarize students with the diverse range of photovoltaic materials and to connect materials properties to aspects of cell design, processing, and performance

EENG 401 / APHY 321 / ENAS 986 Semiconductor Silicon Devices and Technology 

This is a theory/laboratory course for students whose interests range from semiconductor devices to IC technology to circuit design, especially those who would like to try their hands at semiconductor Si device fabrication and characterization.

The theory part will cover the principles of semiconductor devices, their design groundrules, and their fabrication science and technology.

The laboratory part is intended to illustrate the fundamentals of semiconductor processing and device characterization. Experimental devices, including Ohmic contacts, Schottky diodes, PN junctions, solar cells, MOS capacitors, and MOSFETs, will be fabricated and measured by students.

EENG 408/ ENAS 509 Electronic Materials

The performance of all systems, circuits, and devices- whether for computation, communication, sensing, or energy conversion- are limited by the properties of their constituent materials. Future breakthroughs in solid state device technology will likely originate from advances in our ability to control the structure and properties of electronic materials. The objectives of this course are to provide a working knowledge of materials science concepts encountered in microelectronics and optoelectronics and to help students connect materials structure with processing techniques, properties, and device performance.
