Vacuum-sublimated Lead Halide Perovskite Optoelectronic Devices
Hao-Wu Lin

Halide perovskites have attracted great attention as promising materials for not only
solar energy conversion but also variety of devices. In this talk, I will discuss the all vacuum
deposition technique for perovskite thin films and devices fabrication. Applications such as
solar cells, ultra-violet photodetectors, artificial retina and artificial synapses for
neuromorphic computing will be shown.

Coupling Design for Low-threshold and High-efficient Kerr Micro-comb Generation
Pei-Hsun Wang;Kuan-Lin Chiang

We theoretically model the threshold dynamics with optimal designs of cavity coupling for micro-comb systems. The minimal threshold is numerically solved and altered from the under-coupled to over-coupled regime in the presence of the nonlinear resonance shift. High efficient combs up to 40% conversion efficiency can be generated.

Ultra-compact Spectrometer Based on Free-form Huygens' Metalens
Chih-Ming Wang;Chen-Yi Yu;Chien-Yuan Han

A PB-phase meta-device consisting of nano-fin on a Si substrate is proposed as a spectrometer with low aberrations The phase distribution of the designed meta-device is the combination of an aspherical lens and blazed grating. Not only focusing and deflecting, the off-axis aberration is also eliminated.

In-plane Optical Anisotropy of Layered GaTe Observed by Photoluminescence and Thermoreflectance Spectroscopy
Ching-Hwa Ho;Mei-Chan Chiou

In-plane optical anisotropy of multilayer GaTe have been characterized by polarized micro-photoluminescence and polarized thermoreflectance near band edge. The experimental results clearly demonstrate an x-polarized band-edge exciton is merely existed near its band gap.

Stacked 2D, 3D and Amorphous Structures for Device Applications
Shih-Yen Lin;Kuan-Chao Chen;Yu-Wei Zhang;Po-Cheng Tsai

Van der Waals epitaxy of 2D and 3D crystals are demonstrated on 2D material surfaces. Extended soaking time and physical deposition would help the formation of leakage-current-free dielectric layers on 2D material surfaces. The hetero-structures thus formed have demonstrated huge potential in device applications.

Surface Enhanced Raman Scattering (SERS) Molecular Sensors with 10-16 M R6G and 10-12 M Adenine Low Detection Limits
Yonhua Tzeng;Ying-Ren Chen;Jiun-Chi Lai;Boyen Huang;Bo-Yi Lin

Graphene nano-islands masked chemical plating of silver on copper exhibits nanoscale gaps desirable for SERS sensors application with 10-16 M R6G and 10-12 M adenine detection limits and excellent reproducibility. Concentration and pH dependent enhancement and shift of adenine SERS peaks enable detection of pico-molar adenine.

Investigation of p-Si/N-Mg0.3Zn0.7O:In Self-powered Heterojunction Photodiodes with Different Indium Doping Concentration
Han-Yin Liu;Hung-Sheng Chu;Kai-Wei Liu;Yu-Xing Zheng;Wei-Ting Chen;Pei-Huang Hsu

This study investigates using mist chemical vapor deposition to deposit indium-doped Mg0.3Zn0.7O thin films with different doping concentration. Then, p-Si/N-Mg0.3Zn0.7O:In heterojunction photodiodes are fabricated. The static and dynamic photoresponse characteristics suggest that the heterojunction photodiodes are operated as self-powered photodiodes since the built-in potential is formed at the heterojunction.

Localized Surface Plasmon Resonance Effect of Gold Nanoparticles Modified TiO2_Graphene Composite Film as Mesoporous Layer for Perovskite Solar Cells
Hsueh-Tao Chou;Tien-Ming Wu;Zi-Heng Lin;Chun-Yu Chu;Guan-Yu Lin;Yao-Chieh Wu

In this research, the electrical modification of electron transport layer (ETL) through using gold nanoparticles (AuNPs) and its localized surface plasmon resonance (LSPR) effect. Second, the optimization of perovskite layer through using different parameters, such as different types of solvents of PbI2, annealing temperatures and annealing time.
