Lin-Di Huang;Chi-Hsien Cheng;Yu-Chueh Hung

In this study, we present the stimulus pulse-dependent responses of DNA biopolymer devices, where the conductivity of the device is controlled by consecutive electrical pulses of different parameters. Device behaviors can mimic the synaptic plasticity in the human brain, paving the way towards biomaterial-based artificial synapses in neuromorphic systems.

An Anti-Opal Hydrogel Sensor for Food Additives Detecting
Hsin Her Yu;Jau-Jhong Yu;Wan-Ling Chen

An anti-opal hydrogel sensor capable of identifying L-Tryptophan (L-Trp) is prepares by combining photonic crystals with molecular imprinting techniques. This sensor has a great exclusive-identification for L-Trp, and its concentration can be predicted from the displacement of its reflective peak and the change of the color coordinate positions.

In this work, CsPb(Br1-xIx)3 quantum dots with different compositions were prepared and the temperature-dependent photoluminescence (PL) measurements were carried out. To investigate the thermal behaviors of peak energy, linewidth, and emission intensity of the PL spectra, the electron-phonon interaction and thermal expansion effect on the band-gap are discussed.

Optical contrast dependence of few-layer MoS2 on the thickness of the oxide layer on silicon
Yu-Chung Chang;Yen-Ting Chen

We developed a method to quickly identify the location and determine the thickness of two-dimensional materials on silicon substrates by selecting the thickness of the oxide layer in between. It is important to find optimum oxide layer parameters for functional devices. The thickness dependence of spectroscopic properties was studied.

High-performance nanostructured p-Cu2O/n-Si heterojunction photodiodes
Chun-Ying Huang;Fang-Chi Lo;Tsung-Chih Wan

A photodetector with a simple structure that uses a nanostructured p-Cu2O/n-Si heterojunction is purposed. This device features a high responsivity of 0.55 A/W at a reverse bias of -5 V. The p-Cu2O/n-Si heterojunction also has a high response speed (<10 ms) because there is a built-in potential within p-n junction

Extraordinary acoustic transmission analysis using simple spring-mass model
Ying-Pin Tsai;Fu-Li Hsiao

Extraordinary acoustic transmission (EAT) is investigated numerically using a
square lattice array (SLA) of both-sides-open disk resonators (BSODRs) in a steel slab immersed in water. The BSODR resonance results in low-frequency EAT, and it is shown that the
BSODR’s resonant behavior can be predicted using a spring-mass model.

We present the characterization of inkjet-printed DNA biomaterial on paper substrates. PL properties and energy transfer efficiency of DNA inks were characterized with different combinations of dyes, deposition orders, and paper substrates. The results suggest that DNA biomaterial may be a promising candidate to be implemented in inkjet printing platform.
