24 Oct 2012   Contributor(s):: Mark Lundstrom, Xingshu Sun
These notes are intended to complement the discussion on pp. 63 – 68 in Fundamentals of Modern VLSI Devices by Yuan Taur and Tak H. Ning [1]. (Another good reference is Semiconductor Device Fundamentals by R.F. Pierret [2].) The objective is to understand how to treat MOS electrostatics without...

MOSC VFB Calculation: Comparison of Theoretical and Simulation Values (Instructor Copy)
05 Feb 2012   Contributor(s):: Stella Quinones
The flatband voltage is calulated based on device physics theory and is compared to the value determined from the simulation of a MOSCapacitor using the MOSCap simulation tool on the nanoHUB.org website. By completing this exercise, the student is able to compare the mathematical model of the...

SCHRED Exercise: MOS Capacitor Analysis
20 Jul 2010   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The objective of this exercise is to examine the influence of semiclassical and quantummechanical charge description on the lowfrequency CVcurves. It also teaches one the influence of polygate depletion on the lowfrequency CVcurves.

Quantum Bound States Exercise
16 Jun 2010   Contributor(s):: Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
Exercise BackgroundQuantummechanical systems (structures, devices) can be separated into open systems and closed systems. Open systems are characterized with propagating or current carrying states. Closed (or bound) systems are described with localized wavefunctions. One such system is a...

06 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise examines the degradation of the total gate capacitance with technology generation due to MaxwellBoltzmann instead of FermiDirac statistics, quantummechanical charge description and depletion of the polysilicon gates.www.eas.asu.edu/~vasileskNSF

Exercise: CV curves for MOS capacitors
02 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise demonstrates to the students how the lowfrequency CV curves in MOS capacitors change with changing the gate workfunction, the oxide thickness and the dielectric constant. It also demonstrates the doping variation of the highfrequency CV curves.NSFNSF
