Finite-Bias Spectroscopy Useful to Determine Bilayer Graphene Bandgap - AZoNano

Gated bilayer graphene with a tunable band gap was characterized by finite-bias transport spectroscopy and temperature-activated transport measurements.

Concurrent control over band gap and the charge carrier density in semiconductors is desirable in photodetectors, highly tunable transistors, and lasers. Bernal-stacked bilayer graphene is a van-der-… [+6090 chars]
