Extrinsic and Intrinsic Charge Trapping at the Graphene/Ferroelectric Interface
Mohammed Humed Yusuf, Bent Nielsen, Matthew Dawber +1
The interface between graphene and the ferroelectric superlattice (PTO/STO) is studied. Tuning the transition temperature through the PTO/STO volume frac…
Nonlinear vs. bolometric radiation response and phonon thermal conductance in graphene-superconductor junctions
Heli Vora, Bent Nielsen, Xu Du
Graphene is a promising candidate for building fast and ultra-sensitive bolometric detectors due to its weak electron-phonon coupling and low heat capacity. In order to realize a p…
Suspended Graphene Ballistic Josephson Weak Links
Naomi Mizuno, Bent Nielsen, Xu Du
The interplay of graphene and superconductivity has attracted great interest for understanding the two-dimensional Dirac Fermion physics and for superconducting device applications…
Bolometric response in graphene based superconducting tunnel junctions
Heli Vora, Piranavan Kumaravadivel, Bent Nielsen +1
We fabricate graphene-TiOx-Al tunnel junctions and characterize their radio frequency response. Below the superconducting critical temperature of Al and when biased within the supe…
Shot Noise in Negative-Differential-Conductance Devices
W. Song, E. E. Mendez, V. Kuznetsov +1
We have compared the shot-noise properties at T = 4.2 K of a double-barrier resonant-tunneling diode and a superlattice tunnel diode, both of which exhibit negative differential-co…
