Effect of defect-induced cooling on graphene hot-electron bolometers
Abdel El Fatimy, Peize Han, Nicholas Quirk +9
At high phonon temperature, defect-mediated electron-phonon collisions (supercollisions) in graphene allow for larger energy transfer and faster cooling of hot electrons than the n…
Ambient Effects on Photogating in MoS2 Photodetectors
Peize Han, Eli Adler, Yijing Liu +5
Atomically thin transition metal dichalcogenides (TMDs) are ideal candidates for ultrathin optoelectronics that is flexible and semitransparent. Photodetectors based on TMDs show r…
Ultra-broadband photodetectors based on epitaxial graphene quantum dots
Abdel El Fatimy, Anindya Nath, Byoung Don Kong +7
Graphene is an ideal material for hot-electron bolometers, due to its low heat capacity and weak electron-phonon coupling. Nanostructuring graphene with quantum dot constrictions y…
Highly Sensitive MoS2 Photodetectors with Graphene Contacts
Peize Han, Luke St. Marie, Qing X. Wang +4
Two-dimensional materials such as graphene and transition metal dichalcogenides (TMDs) are ideal candidates to create ultra-thin electronics suitable for flexible substrates. Altho…
Epitaxial graphene quantum dots for high-performance THz bolometers
A. El Fatimy, R. L. Myers-Ward, A. K. Boyd +3
Light absorption in graphene causes a large change in electron temperature, due to low electronic heat capacity and weak electron phonon coupling [1-3], making it very attractive a…
Low Carrier Density Epitaxial Graphene Devices On SiC
Yanfei Yang, Lung-I Huang, Yasuhiro Fukuyama +6
Monolayer epitaxial graphene (EG) grown on hexagonal Si-terminated SiC substrates is intrinsically electron-doped (carrier density is about 10^13 cm^(-2)). We demonstrate a clean d…
