This paper describes an RGB-infrared (IR) organic CMOS image sensor with electrically controllable IR sensitivity. The sensitivities of all the pixels in sensor, which has structure two directly stacked layers a high resistance ratio, are simultaneously controlled by changing applied voltage to films. fabricated pixel pitch 3 μm, 2.1 Mpixels (1920 × 1080) both RGB and regions. can switch between color imaging modes frame without requiring mechanically retractable IR-cut filter.
The use of infrared (IR) imaging to view scenes otherwise invisible the human eye, simultaneously with visible-spectrum imaging, is increasingly interest for various applications such as in-vehicle, surveillance, and agricultural security cameras. loss spatial resolution in conventional RGB-IR sensors causes aliasing, because IR pixels are segmented within provided effective pixel area [1,2]. 3-D stacking photodiode arrays has been reported another strategy capture [3]; however, need bonding...
Atomic transfer through the interfaces upon Bi precipitation is specifically investigated with respect to vacancy-sized free volumes for a Sn65.4Bi34.6 eutectic alloy of highly heterogeneous system by making full use backscattering electron imaging, small-angle x-ray scattering, diffraction, and positron annihilation spectroscopy. Bi-rich particles ∼100 nm segregated nanocrystallites ∼30 are observed cooled at cooling rate 10−1 K s−1. intergrow each other up ∼1 µm ∼55 nm, respectively, an...
Positron lifetime spectroscopy was conducted for natural minerals to investigate open-nano pores. Positronium (Ps) formation occurs with ortho-positronium (o-Ps) intensities ranging from a few % 20 and size distributions of nano pores are evaluated o-Ps lifetimes. The results will be discussed respect processes influenced by earth's environment.
Abstract. In Japan, the frequency of sudden heavy rain events has recently increased, causing slope failures that in turn increase rates damage to transit infrastructure such as railways and roads. To reduce this damage, there is a need identify locations near railroad tracks are at risk failure. Thus, an assessment predicts whether or not will occur due external forces rains required, rather than simple relative based on identifying similar those damaged previous events. study, we developed...
Positron annihilation lifetime spectroscopy was conducted for a synthetic saponite to investigate hydration and dehydration behaviour occurring in nanoscale interlayer spaces. Long positron of ∼ 24 ns observed with the intensity 8 % when sample is evacuated at 10−5 Torr. The radius open nanospace evaluated from 10 Å, which corresponds spaces saponite. increases up 13 after baking 423 K h under vacuum. present results imply that powerful tool behavior through local structural changes clay minerals.
Conventional vacuum deposition onto a substrate coated with self-assembled monolayer (SAM) was used to produce arrays of hemispherical nanostructures composed organic semiconducting materials low molecular weight. The had minimum diameter 40 nm, indicating that cluster formation occurred in the gas phase during deposition. size and shape were controlled by underlying SAMs, materials, film thickness temperature.

Abstract Usually, the resonant filter is composed of several resonators made dielectric and metal, applied to high‐frequency bandpass filters (BPFs). Although a has simple structure, it very difficult obtain optimal geometry experimentally, because its characteristic greatly influenced by material structure.
