Ping-Yu Lin, National Taipei University of Technology (Taiwan), National Cheng Kung University (Taiwan); Wen-Jeng Ho, National Taipei University of Technology (Taiwan); Hung-Pin Shiao, Win Semiconductor Corp (Taiwan)

Embedding single and double indium nanoparticles (In-NPs) sheets within a 52-nm
thick TiO2 anti-reflective layer, the conversion efficiency of InGaP/GaAs/Ge triple-junction
solar cells (3J-SCs) is significantly enhanced due to plasmonic effects. The distance between
In-NPs sheet and 3J-SC effecting on the conversion efficiency was also investigated.
Therefore, the cell with double In-NPs sheets, which with the distance of 10 nm and 42 nm
away from the surface of 3J-SC, obtained the lowest reflectance and highest EQE, as well as
resulting in a remarkable 33.22% increasing in conversion efficiency, due to the combination
of near-field and far-field plasmonic effects.

Chin-An Hsu Optoelectronic Properties of (PEA)2PbI4 Two-Dimensional Perovskite Nanoflakes
Chin-An Hsu, Ti-Kai Chou, National Taiwan University (Taiwan); Yu-Chiang Chao, National Taiwan Normal University (Taiwan); I-Chun Cheng, National Taiwan University (Taiwan)

Two-dimensional (2D) perovskites have been regarded as potential active materials for optoelectronic devices. Perovskite flakes at nanoscales in thickness have shown distinct optoelectronic properties, such as higher fraction of radiative recombination, in comparison to their bulk counterparts. However, nanoflakes of 2D perovskites are seldom demonstrated and investigated. In this research, we successfully fabricate PEA2PbI4 (2D) Ruddlesden-Popper (RP) perovskite nanoflakes of 11 nm by using a facile three-step method, and their optoelectronic and field-effect characteristics are studied.

Minh Loi Le Current injected gain spectrum of bulk and tri-layer MoS2 as an optical amplifier
Minh Loi Le, Ting Wei Chen, National Pingtung University (Taiwan)

We numerically investigate the optical gain spectrum of the bulk and tri-layer of molybdenum disulfide functioned as an optical amplifier. In room temperature, the bulk has a minimum interaction photon energy at the band gap (1.23 eV) with a threshold injected current density ~3 kA/cm2. For the 2D tri-layer film, the minimum interaction photon energy is lifted to 2.09 eV due to the quantum-well structure, and the threshold injected current density is ~1.9 kA/cm2 which is significantly lower than that in bulk. The dependence of the optical gain profiles on the temperature and injected current density are also investigated.

dispersed in a polymer matrix, have opaque state or transparent state. Without external electric
field, the refractive index of liquid crystal droplets do not match that of the polymer matrix, so
that so that the light is strongly scattered when it passes through the PDLC film. By tuning the

Yung-Lan Chuang Photoelectrochemical Characteristics of photoelectrodes made of n-GaN Nanopillars capped with Ni(OH)2 Nanosheets
Yung-Lan Chuang, Wei-Wei Tung, National Cheng Kung University (Taiwan); Ming-Lun Lee, Southern Taiwan University of Science and Technology (Taiwan); Jinn-Kong Sheu, National Cheng Kung University (Taiwan)

In photoelectrochemical reactions, the performance of n-GaN nanopillar photoelectrodes declines due to photocorrosion. This study explores enhancing stability during PEC reactions. Photoelectrodes of n-GaN with a Ni(OH)2 capping layer showed more durability than Ni(OH)2-free ones. In particular, the effect of a NiO seed layer on Ni(OH)2 nanosheet coverage on n-GaN was evaluated. Enhanced stability is mainly attributed to the Ni(OH)2 coating, passivating defects in n-GaN and facilitating carrier transport to the electrolyte, suppressing photocorrosions.

Min-Yang Lu The Optical and Mechanical Properties of Tungsten Doped Vanadium Dioxide Thin Films
Min-Yang Lu, Feng Chia University (Taiwan)

In this work, tungsten-doped vanadium oxide (VO2) films were deposited by electron beam evaporation associated with ion beam-assisted deposition.The optical and mechanical properties of these VO2 films at different tungsten doping concentrations were investigated. The results show that the visible light transmittance and residual stress of vanadium oxide films decrease with the increase of doping tungsten concentration. When the VO2 sample with a doping concentration of 5% is heated above 55 °C, the transmittance drops sharply, which may be due to the phase transition to a metal phase, and the phase transition temperature is estimated to be 55 °C.

This report investigates the potential of laser ionization programming (hereafter LIP) to enhance the programming capability of a non-volatile memory (NVM) capacitor with lightly doped substrate, specifically a silicon-silicon oxide-silicon nitride-silicon oxide-silicon (SONOS) type. Laser-generated charges in the substrate of a SONOS-type NVM capacitor with lightly doped substrate (hereafter LDSONOSC) make them more easily programmable under laser ionization. The focus is on the performance of UV LIP on an LDSONOSC, which utilizes a UV transparent conductive gate and UV transparent nanocrystalline high-k gate dielectric, enabling the UV-LIP-LDSONOSC to store more data in a smaller space, ultimately enhancing their efficiency.

Chiao-Li Chang, Zi-Chun Tseng, Vincent K. S. Hsiao, National Chi Nan University (Taiwan)

This study investigates the photoelectrochemical (PEC) behavior of porous silicon (PSi) and its nickel (Ni)-coated hybrid system. Ni-coating significantly enhances PEC performance, attributed to catalytic activity, improved light absorption, and altered carrier transport. Scanning electron microscopy (SEM) analysis reveals distinct structures on PSi surfaces before and after Ni-coating, correlating with enhanced PEC performance due to intensified carrier mobility. Varying Ni coating times show optimal PEC at 15 minutes, potentially due to suitable structures enhancing electron-hole pairs separation.
