Students can explain the electrical functioning of diodes and MOSFETS by applying the underlying physics models.
After this course the student:
- understands the concept “depletion approximation” and charge conservation
- is able to apply Gauss’s law for determining the electric field/potential
- understands the formation of the pn-junction diode and MOS capacitor at thermal equilibrium
- understands the rectifying behavior of the pn-junction diode
- is able to model the electrical characteristics of the pn-junction diode and MOSFET in steady state condition and during switching
- understands the concept of threshold voltage and built-in voltage
- knows the concept heterojunctions
- understands the notion of contact resistance
- recognizes the different aspects of “transistor performance”
- relates physical dimensions to transistor action
- recognizes physical limitations in the transistor architecture
- has a basic notion of the IC technology and development
