TCAD simulations using SCHRED [15] or
ISE, …., were used to support our analysis
and compute the inversion carrier profiles in
the devices.

Use in Education
The nanoHUB has proven itself to be an extremely valuable tool
for education and research. …We have used the Resonant Tunneling
Diode simulator and the MSL simulator on the nanoHUB for homework
exercises and mid-term exams. A class survey of the use of the
nanoHUB simulation engines had shown that the experience is quite
positive. The staff at the nanoHUB has been very responsive in
supporting our class activities in a professional manner.

Using our strengths to reach
minorities
• nanoHUB.org delivers research and education
resources cheaply
– No user travel required
– Institution already has neecded Internet infrastructure
– Incremental cost of access per user near zero
• nanoHUB.org collects data for assessment of quantity
and quality of minority engagement
