Mechanical control of quantum transport in graphene
A. C. McRae, G. Wei, L. Huang +3
Two-dimensional materials (2DMs) are fundamentally electro-mechanical systems. Their environment unavoidably strains them and modifies their quantum transport properties. For insta…
Non-Classical Longitudinal Magneto-Resistance in Anisotropic Black Phosphorus
Francesca Telesio, Nicholas Hemsworth, William Dickerson +11
Resistivity measurements of a few-layer black phosphorus (bP) crystal in parallel magnetic fields up to 45 T are reported as a function of the angle between the in-plane field and…
Phosphorus oxide gate dielectric for black phosphorus field effect transistors
W. Dickerson, V. Tayari, I. Fakih +7
The environmental stability of the layered semiconductor black phosphorus (bP) remains a challenge. Passivation of the bP surface with phosphorus oxide, POx, grown by a reactive io…
Quasi-two-dimensional thermoelectricity in SnSe
V. Tayari, B. V. Senkovskiy, D. Rybkovskiy +14
Stannous selenide is a layered semiconductor that is a polar analogue of black phosphorus, and of great interest as a thermoelectric material. Unusually, hole doped SnSe supports a…
Dephasing in strongly anisotropic black phosphorus
N. Hemsworth, V. Tayari, F. Telesio +9
Weak localization was observed and determined in a black phosphorus (bP) field-effect transistor 65 nm thick. The weak localization behaviour was found to be in excellent agreement…
Giant Electron-hole Charging Energy Asymmetry in Ultra-short Carbon Nanotubes
A. C. McRae, V. Tayari, J. M. Porter +1
Making full usage of bipolar transport in single-wall carbon nanotube (SWCNT) transistors could permit the development of two-in-one quantum devices with ultra-short channels. We r…
Dual gate black phosphorus velocity modulated transistor
V. Tayari, N. Hemsworth, O. Cyr-Choinière +3
The layered semiconductor black phosphorus has attracted attention as a 2D atomic crystal that can be prepared in ultra-thin layers for operation as field effect transistors. Despi…
Tailoring 10 nm Scale Suspended Graphene Junctions and Quantum Dots
V. Tayari, A. C. McRae, S. Yigen +3
The possibility to make 10 nm scale, and low-disorder, suspended graphene devices would open up many possibilities to study and make use of strongly coupled quantum electronics, qu…
Two-Dimensional Magnetotransport in a Black Phosphorus Naked Quantum Well
V. Tayari, N. Hemsworth, I. Fakih +5
Black phosphorus (bP) is the second known elemental allotrope with a layered crystal structure that can be mechanically exfoliated down to atomic layer thickness. We have fabricate…
Electronic Thermal Conductivity Measurements in Intrinsic Graphene
S. Yiğen, V. Tayari, J. O. Island +2
The electronic thermal conductivity of graphene and 2D Dirac materials is of fundamental interest and can play an important role in the performance of nano-scale devices. We report…
Few-hundred GHz Carbon Nanotube NEMS
J. O. Island, V. Tayari, A. C. McRae +1
We study 23 to 30 nm long suspended single-wall carbon nanotube quantum dots and observe both their stretching and bending vibrational modes. We use low-temperature DC electron tra…
Ultra-short suspended single-wall carbon nanotube transistors
J. O. Island, V. Tayari, S. Yigen +2
We describe a method to fabricate clean suspended single-wall carbon nanotube (SWCNT) transistors hosting a single quantum dot ranging in length from a few 10s of nm down to $\appr…
