The Influence of Surface Polarities on The Optical Characteristics of Mono-layer MoS2
Hon-Chin Huang;Po-Cheng Tsai;Shih-Yen Lin;Si-Chen Lee
We have transferred the mono-layer MoS2 films grown on sapphire substrates to different substrates. Enhanced PL intensity is observed for the MoS2 film transferred to the HMDS pre-treated SiO2/Si substrate, which indicates that surface polarities play an important role for the optical characteristics for 2D materials.

Study of Graphene-Metal Interactions on Aluminum-Based Plasmonic Nanolasers
Yi-Cheng Chung;Heng Li;Tien-Chang Lu;Kuo-Ping Chen;Tzy-Rong Lin
The Drude–Lorentz model was used to describe graphene and analyze its charge transfer effect with regard to the performance of aluminum-based plasmonic nanolasers. The variation in charge density influenced the optical properties of aluminum and demonstrated the effect of charge transfer on the characteristics of surface-plasmon-polariton (SPP) modes.

Mechanism of THz Photoacoustic Generation through Ultra-thin Nickel Films
Kuan-Yu Chou;Jinn-Kong Sheu;Chi-Kuang Sun
Thin metal films have been widely adopted to generate ultra-high frequency hypersound combined with femtosecond or picosecond optical excitations. We demonstrate THz photoacoustic generation by using various thickness ultra-thin Nickel films. The mechanism of the acoustic waves generation by Ni film will be discussed.

ReS2 - The Study of In-Plane Optical and Electrical Anisotropy on a 2D Dichroic Material
Ching-Hwa Ho
In this work, ReX2 (X=S, Se) series 2D materials have been successfully grown by chemical vapor transport method. Excitonic emissions, optoelectronic properties and photocatalytic behavior of layered ReX2 with specific in-plane anisotropy have been clearly demonstrated herein.

Current Modulation of Graphene-Insulator-Metal Nanolasers
Jia-Wei Chen;Chu-Yuan Hsu;Heng Li;Kuo-Bin Hong;Tien-Chang Lu
We have taken the advantages of graphene and constructed a graphene-insulator-metal nanolaser device that could be modulated by applying current through graphene under being optically pumped. The magnitude of the modulation are dependent on the angle of the nanowire with respect to the current direction

Color Conversion between WSe2 Atomic Layers and Coreshell Quantum Dots with Plasmonic Metasurface
Hao-Hsuan Chiu;Chen-An Lin;Cheng-Yuan Chen;Hsiang-Ting Lin;Chiao-Yun Chang;Hao-Chung Kuo;Min-Hsiung Shih
The color conversion between quantum dots and the tungsten diselenide atomic layer was investigated with the plasmonic metasurface. The metasurface consists a series of silver nanodisks, exhibits the localized surface plasmon resonances (LSPR) around the interfaces, and leads to optical emission enhancement and color conversion manipulation between WSe2 and QDs.

A strain-gauge random laser
Pei-Jung Wu;Ting-Wei Yeh;Nagarjuna Arjun;Chieh-Chi Tseng;Jui-Yun Yi;Ya-Ju Lee
A random laser that uses the ZnO nanorods randomly orientated on a flexible polyimide substrate as disorderedly optical scatterers to stimulate coherent random lasing actions. Our random laser functions as a stable and durable optical strain gauge with a gauge factor of ≈37.7 under a bending strain of 40%.
