The BIOFET-SIM Web Interface 1.0 BioFET-SIM

Created by Luca De Vico

Follow this for help on the relationship between Thomas-Fermi length, effective charge carrier mass, and charge carrier density.

This web interface presents only a simplified version of BioFET-SIM. Please check the help page for more information and to download the interactive program. Currently under maintanance.

BioFET-SIM is now also available as a free App on the App Store! Coming back soon! BioFET-SIM Available on the App Store
