Propagation-induced limits to high harmonic generation in 3D Dirac semimetals
Jeremy Lim, Yee Sin Ang, Lay Kee Ang +1
3D Dirac semimetals (DSMs) are promising materials for terahertz high harmonic generation (HHG). We show that 3D DSMs' high nonlinearity opens up a regime of nonlinear optics where…
Absence of Space-Charge-Limited Current in Unconventional Field Emission
Cherq Chua, Chun Yun Kee, Yee Sin Ang +1
For field emission (FE), it is widely expected that its emitting current density will become space-charge-limited current (SCLC) due the built-up of charge in-transit within a…
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 a Concentrated High-Efficiency Thermionic Solar Cell Enabled by Graphene Collector
Xin Zhang, Xiaohang Chen, Jinchan Chen +2
We propose a concentrated thermionic emission solar cell design, which demonstrates a high solar-to-electricity energy conversion efficiency larger than 10\% under 600 sun, by harn…
Quantum Transport in Two-Dimensional WS with High-Efficiency Carrier Injection Through Indium Alloy Contacts
Chit Siong Lau, Jing Yee Chee, Yee Sin Ang +8
Two-dimensional transition metal dichalcogenides (TMDCs) have properties attractive for optoelectronic and quantum applications. A crucial element for devices is the metal-semicond…
Semiconductor-to-metal transition in bilayer MoSiN and WSiN with strain and electric field
Qingyun Wu, Liemao Cao, Yee Sin Ang +1
With exceptional electrical and mechanical properties and at the same time air-stability, layered MoSi2N4 has recently draw great attention. However, band structure engineering via…
