Designer Edge States in Fractional Polarization Insulators
Wei Jie Chan, Peihao Fu, L. K. Ang +1
We theoretically investigated the topological-protected edge states (TESs) in an anisotropic honeycomb lattice with mirror and chiral symmetries, characterized by an alternative to…
Modeling of electric double layer at solid-liquid interface with spatial complexity
Cherq Chua, Chun Yun Kee, L. K. Ang +1
Electrical double layer (EDL) is formed when an electrode is in contact with an electrolyte solution, and is widely used in biophysics, electrochemistry, polymer solution and energ…
Thermal-Field Electron Emission from Three-Dimensional Topological Semimetals
Wei Jie Chan, Yee Sin Ang, L. K. Ang
A model is constructed to describe the thermal-field emission of electrons from a three-dimensional (D) topological semimetal hosting Dirac/Weyl node(s). The traditional thermal…
Designing Efficient Metal Contacts to Two-Dimensional Semiconductors MoSiN and WSiN Monolayers
Qianqian Wang, Liemao Cao, Shi-Jun Liang +8
Metal contacts to two-dimensional (2D) semiconductors are ubiquitous in modern electronic and optoelectronic devices. Such contacts are, however, often plagued by strong Fermi leve…
Electrical Contact between an Ultrathin Topological Dirac Semimetal and a Two-Dimensional Material
Liemao Cao, Guanghui Zhou, Qingyun Wu +4
Ultrathin films of topological Dirac semimetal, NaBi, has recently been revealed as an unusual electronic materials with field-tunable topological phases. Here we investigate t…
Super-Andreev reflection and longitudinal shift of pseudospin-one fermions
Xiaolong Feng, Ying Liu, Zhi-Ming Yu +4
Novel fermions with a pseudospin-1 structure can be realized as emergent quasiparticles in condensed matter systems. Here, we investigate its unusual properties during the Andreev…
Generalized high-energy thermionic electron injection at graphene interface
Yee Sin Ang, Yueyi Chen, Chuan Tan +1
Graphene thermionic electron emission across high-interface-barrier involves energetic electrons residing far away from the Dirac point where the Dirac cone approximation of the ba…
Universal Scaling Laws in Schottky Heterostructures Based on Two-Dimensional Materials
Yee Sin Ang, Hui Ying Yang, L. K. Ang
We identify a new universality in the carrier transport of two-dimensional(2D)-material-based Schottky heterostructures. We show that the reversed saturation current (…
Valleytronics in merging Dirac cones: All-electric-controlled valley filter, valve and universal reversible logic gate
Yee Sin Ang, Shengyuan A. Yang, C. Zhang +2
Despite much anticipation of valleytronics as a candidate to replace the ageing CMOS-based information processing, its progress is severely hindered by the lack of practical ways t…
Generalized Fowler-Nordheim field-induced vertical electron emission model for two-dimensional materials
Yee Sin Ang, M. Zubair, K. J. A. Ooi +1
Current theoretical description of field-induced electron emission remains mostly bounded by the classic Fowler-Nordheim (FN) framework developed nearly one century ago. For the em…
