MOSCap Learning Materials

by Saumitra Raj Mehrotra, Dragica Vasileska, Gerhard Klimeck, Alejandra J. Magana


By completing the MOSCap Lab in ABACUS - Assembly of Basic Applications for Coordinated Understanding of Semiconductors, you will be able to:

a) understand operation of Metal-Oxide-Semiconductor using energy band diagrams.

b) study the effect of interface traps, work function, oxide thickness etc on Capacitance-Voltage output.

c) understand MOS-C C-V characteristics in low and high frequency limits.

The specific objectives of the MOSCap Lab are:
