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.
