It is widely believed that the single-photon gain (SPG) of passive-quenched single-photon avalanche diodes (PQ-SPADs) is given by the product of the junction capacitance ( ${C}_{d}$ ) and the overvoltage ( ${V}_{\textsf {ov}}$ ) applied to the SPAD a

A large shift of the localized surface plasmon resonance (LSPR) spectrum of gold nanoparticles was attained by electrochemical oxidation of the nanoparticle surface. This oxidation occurred in the cell, which consisted of a pair of indium tin oxide (

A half-V-shaped switching ferroelectric liquid crystal (FLC) is a promising candidate for fast response displays. In the half-V FLC display, a liquid crystal with a chiral nematic–chiral smectic C phase transition is used, and the smectic layer is

Parameters in an equivalent circuit model (ECM) are calculated from measurement data of voltage holding ratio (VHR), D-E hysteresis curve and response time for asymmetric half-V mode ferroelectric liquid crystals. In the calculation, a formulation of

Thresholdless antiferroelectric liquid crystal (TLAF) characterized by V-shaped switching in a smectic liquid crystal is very attractive for active matrix driving, but the switching mechanism is not fully understood. We have studied electro-optical p

Polarized infrared spectroscopy was applied to the analysis of rubbed polyimide films. N2 purge of a sample chamber and increased substrate thickness enhanced the detection sensitivity. Dichroic differences were measured for the rubbed polyimide film
