$ EE130 Fall 2005 MOSFET Project: MEDICI DECK

$ This is the device simulation deck for MEDICI. In here you will ramp 
$ drain and gate voltages and plot IV characteristics. Some of the initial 
$ statements to start the simulations have been provided to you. You will 
$ be required to fill in the rest.

$ load the TSUPREM4 file
 mesh infile=EE130nmos.str tsuprem4

$ specify contact materials, we're using n+ poly gate
 contact name=drain      neutral
 contact name=gate       n.poly
 contact name=source     neutral
 contact name=substrate  neutral

$ load the appropriate models
 models lsmmob fldmob fermidir

$ Begin solve statements
$ solve the equillibrium state of the device with no carriers
 symbolic carriers=0
 solve initial

$ now begin to ramp gate and drain biases
$ both electron and hole current will be solved
 symbolic newton carriers=2

$ insert rest of solve statements to generate IV curve desired
$solve v(gate)=0
