Giant anisotropic photocurrent modulated by strain in type-II Weyl semimetal Td-MoTe2
Xinru Wang, Ying Ding, M. N. Chen +3
We build a Cu-MoTe2-Cu device model and use first-principles density functional theory to study the transport properties of single-layer Td-MoTe2. We obtained the effect of strain…
Valley-dependent transport in strain engineering graphene heterojunctions
Fei Wan, Xinru Wang, Liehong Liao +6
We study the effect of the strain on the band structure and the valley-dependent transport property of graphene heterojunctions. It is found that valley-dependent separation of ele…
Higher Chern Number States in Curved Periodic Nanowires
Zhuo Bin Siu, Seng Ghee Tan, Mansoor B. A. Jalil
The coupling between the spin and momentum degrees of freedom due to spin-orbit interactions (SOI) suggests that the strength of the latter can be modified by controlling the motio…
Strain-Modulated Graphene Heterostructure as a Valleytronic Current Switch
Maverick Chauwin, Zhuo Bin Siu, Mansoor Bin Abdul Jalil
Strain engineering is a promising approach for suppressing the OFF-state conductance in graphene-based devices that arises from Klein tunnelling. In this work, we derive a comprehe…
Critical hybridization of skin modes in coupled non-Hermitian chains
S M Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +2
Non-Hermitian topological systems exhibit a plethora of unusual topological phenomena that are absent in the Hermitian systems. One of these key features is the extreme eigenstate…
Unconventional node voltage accumulation in generalized topolectrical circuits with multiple asymmetric couplings
S M Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +2
A non-Hermitian system is characterized by the violation of energy conservation. As a result of unbalanced gain or loss in the forward and backward directions due to non-reciprocal…
Non-Hermitian topological phases and exceptional lines in topolectrical circuits
S M Rafi-Ul-Islam, Zhuo Bin Siu, Mansoor B. A. Jalil
We propose a scheme to realize various non-Hermitian topological phases in a topolectrical (TE) circuit network consisting of resistors, inductors, and capacitors. These phases are…
