Can we define unique effective masses in Si nanowires?
06 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise teaches the users that for small nanostructures the concept of the effective mass becomes vague and in order to properly describe nanostructures one has to take into account the numerically calculated dispersion relation. This is clearly illustrated on the example of Si nanowires with different cross sections.NSF

Schred: Exercise 1
06 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise illustrates basic SCHRED capabilities for modeling MOS capacitors and also illustrates how the bound states distribution in energy changes with doping. The average distance of the carriers calculated semiclassically and quantummechanically is also examined since it is important parameter that contributes to the effective oxide thickness that determines the total gate capacitance and, therefore, the device transconductance.
