Lecturers: Prof Daping Chu (dpc31)

Dr Man Yi Ho (myh20)

Timing and Structure:Lent Term. 14 lectures (including examples classes).

Assessment: 100% exam

Prerequisites:   3B5 and 3B6 useful


The aims of the course are to:

  • introduce the student to the theory , and design of MOS Field-Effect Transistors (MOSFETs), based on both single crystal and thin-film materials.
  • introduce examples of applications of MOSFETs


As specific objectives, by the end of the course students should be able to:

  • understand MOSFET theory and standard approximations.
  • correlate material properties and conduction mechanisms with the MOSFET electrical characteristics, for single crystal, amorphous and polycrystalline devices.
  • understand the basic properties of ferroelectrics and its application for memory devices.
  • understand the concept of giant magneto-resistance and its applications including non-volatile memory devices.
  • understand the operation of liquid crystal displays.
  • understand the construction and operation of micromechanical displays, and other emerging display technologies.

Syllabus & Lecture Notes

The aim of this module is to introduce the student to the theory, and design of MOS Field-Effect Transistors (MOSFETs), based on both single crystal and thin-film materials. This will be followed by application examples, including chemical/biological sensors in sensor technologies,ferroelectric and magnetic random access memories (FRAM and MRAM) in non-volatile memory technologies, and active matrix liquid crystal displays and micromechanical displays in display technologies. Emphasis will be placed on both device physics and application technology.



    Non-Volatile Memory Devices and Displays (5L)

    Ferroelectrics and ferroelectric random access memories; Giant magneto-resistance (GMR) and magnetic random access memories. Directly driven liquid crystal displays; Active matrix liquid crystal displays and projectors; Micromechanical projectors; Other types of displays and emerging technologies.
