Surface exciton polaritons: a promising mechanism for sensing applications
Yi Xu, Lin Wu, L. K. Ang
The possibility of constructing a surface exciton polariton (SEP) based sensor at room temperature is explored. The proposed SEP sensor is based on the Kretschmann-Raether configur…
Fractional Fresnel coefficients for optical absorption in femtosecond laser-induced rough metal surfaces
Muhammad Zubair, Yee Sin Ang, Kelvin J. A. Ooi +1
The surface morphology of metal influences its optical absorptivity. Recent experiments have demonstrated that the femtosecond laser induced surface structures on metals could be d…
Asymmetric Schottky Contacts in Bilayer MoS2 Field Effect Transistors
Antonio Di Bartolomeo, Alessandro Grillo, Francesca Urban +8
We discuss the high-bias electrical characteristics of back-gated field-effect transistors with CVD-synthesized bilayer MoS2 channel and Ti Schottky contacts. We find that oxidized…
Thickness dependence of space-charge-limited current in spatially disordered organic semiconductors
Muhammad Zubair, Yee Sin Ang, Lay Kee Ang
Charge transport properties in organic semiconductors are determined by two kinds of microscopic disorders, namely energetic disorder related to the distribution of localized state…
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 (…
