Polarization-mediated Debye-screening of surface potential fluctuations in dual-channel AlN/GaN high electron mobility transistors
David A. Deen, Ross Miller, Andrei Osinsky +5
A dual-channel AlN/GaN/AlN/GaN high electron mobility transistor (HEMT) architecture is proposed, simulated, and demonstrated that suppresses gate lag due to surface-originated tra…
Pinning-induced pn junction formation in low-bandgap two-dimensional semiconducting systems
David A. Deen
A model is presented for junction formation near metal-semiconductor contacts in two-dimensional semiconducting systems such as graphene. Carrier type switching occurs in a re…
Suppression of Surface-Originated Gate-Lag by a Dual-Channel AlN/GaN HEMT Architecture
David A. Deen, David F. Storm, D. Scott Katzer +2
A dual-channel AlN/GaN high electron mobility transistor (HEMT) architecture is demonstrated that leverages ultra-thin epitaxial layers to suppress surface-state related gate lag.…
Graphene-based quantum capacitance wireless vapor sensors
David A. Deen, Eric J. Olson, Mona A. Ebrish +1
A wireless vapor sensor based upon the quantum capacitance effect in graphene is demonstrated. The sensor consists of a metal-oxide-graphene variable capacitor (varactor) coupled t…
