Effect of channel positioning on the 1∕ f noise in silicon-on-insulator metal-oxide-semiconductor
M von Haartman, M Oestling,Journal of Applied Physics, 2007 - link.aip.org...
TCAD simulations using SCHRED [15] or ISE, …., were used to support our analysis and compute the inversion carrier profiles in the devices.
• Same behavior across all similar converted tools • User’s don’t have to download/install software

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.
