Office hours: 3:40-4:30 pm MW, 10:40-11:30 pm TTh. (Appointments available at other times if you have a conflict with scheduled office hours. They should be made in advance).

Catalog Description: Prerequisite: EEE 531. (If you did not take this course at ASU, please check with me to confirm that you have the equivalent background). Topics: Advanced MOSFET’s, charge-coupled devices, solar cells, photodetectors, light-emitting diodes, microwave diodes, and modulation-doped structures.

Required Background: Quantum mechanics is not required for this course and will be used only sparingly (but is required for all more advanced courses in this area, and should be taken as early as possible in your program). A graduate level background in transport and recombination theory, semiconductor electrostatics, pn junction diodes, bipolar transistors, and MOS capacitors and transistors, such as that in EEE 531, is required.

Required text:

S.M. Sze and K.K. Ng, Physics of Semiconductor Devices, 3rd ed. (Wiley, 2007).

We will cover portions of Chapters 3,5,7, 9-10, and 12-13, although I will not follow the book closely in all of the lectures. Readings may be assigned from this text, and occasionally from other sources such as books and journal papers.

Grading:Two hour exams...... 50%

Final exam...... 30%

Homework...... 20%

EXAMS MUST BE TAKEN AT THE SCHEDULED TIMES. NO LATE HOMEWORK WILL BE ACCEPTED.

Policies: Studying in small groups is permitted, but homework must be completed individually. Collaboration on homework, or use of old homework papers or solution manuals is considered cheating. Cheating on examinations and any form of plagiarism are strictly forbidden.

Calculator Policy: Scientific calculators are required for all exams. Preferably, they should be nonprogrammable. If they are programmable, you should be prepared to show me how to erase their memory completely at the start of each exam or you will not be permitted to use them. Of course, no sharing of calculators or other materials is permitted during exams.

APPROXIMATE SYLLABUS:

The emphasis of this course will be on a survey of advanced Si and compound semiconductor device physics, especially heterojunctions and metal-semiconductor junctions; high frequency transistors including heterojunction bipolar transistors, JFET’s, and MESFET’s; and microwave and optical devices. Specific topics will be emphasized depending on student interest.

Topics will be selected from the following, as time permits:

I.Semiconductor heterojunctions (classification, band offsets, thermodynamic forces for carrier redistribution, electrostatics, pseudomorphic structures).

II. Transport in heterojunctions and metal-semiconductor junctions (vertical transport via thermionic emission, field-aided thermionic emission, field emission, and diffusion theory; two-dimensional carrier gases, modulation doping, and lateral transport; applications of heterojunctions and Schottky diodes).

III. Bipolar and heterojunction bipolar transistors (operational principle and basic theory, high level injection, Ebers-Moll and Gummel-Poon models, secondary effects, high frequency behavior, use of heterojunctions to enhance device characteristics).

IV. Nonequilibrium MOS devices, including semiconductor memories and CCD devices.

V.Junction and metal-semiconductor field effect transistors (comparative analysis, gradual channel theory, high frequency behavior, velocity saturation effects, noise properties).

VI.Transit-time diodes (IMPATT structures, phase relations, BARITT and TRAPATT diodes).

VII.Transferred-electron devices (transferred electron effect, charge instabilities, LSA mode, hybrid mode, transit mode).

VIII.Light-emitting diodes (nature of optical transitions, materials considerations, internal and external quantum efficiencies, modulation).

IX.Semiconductor lasers (spontaneous and stimulated emission, Einstein A and B coefficients, optical modes, criterion for lasing, heterostructures, device structures and geometries, single-frequency lasers and applications to fiber-optic communications, modulation).

X.Photodetectors and solar cells (photoconductive and photovoltaic detectors, noise considerations, device structures and quantum efficiency, avalanche photodiodes, solar cell efficiency, surface recombination effects, tandem structures, materials systems).
