: We developed a low parasitic light sensitivity (PLS) and low dark current 2.8 μm global shutter pixel. We propose a new inner lens design concept to realize both low PLS and high quantum efficiency (QE). 1/PLS is 7700 and QE is 62% at a wavelength of 530 nm. We also propose a new storage-gate based memory node for low dark current. P-type implants and negative gate biasing are introduced to suppress dark current at the surface of the memory node. This memory node structure shows the world smallest dark current of 9.5 e/s at 60 °C.

The Proposed Specifiers for Conduct Disorder (PSCD) is a promising novel scale that measures psychopathic traits and includes an additional conduct disorder factor that taps the antisocial dimension of psychopathy. The current study sought to broaden the application of PSCD by examining the factor structure, convergent and discriminant validity, and connections to delinquency in a young adult sample ( = 450; = 31.91 years, = 13.

Current understanding of the histology of the dermoskeleton of tetrapods comes from fossilized and recent remains of skulls, osteoderms, carapace, plastron and other postcranial material which were always investigated using linear cross polarized light (LCPL) microscopy. The pectoral girdle of vast majority of non-amniote tetrapods, including temnospondyls evolved large ventrally located dermal bones- the interclavicle and a pair of clavicles. Despite that, there is a lack of information about the bone tissue structure from these postcranial dermal bones.

This study focuses on enhancing the performance of photodetector through the utilization of inorganic perovskite material. It emphasizes that the unique properties of perovskite materials contribute to the superior performance of the photodetector. The focus is on the design and enhancement of CsSnI-based photodetector having graphene oxide (GO) and PCBM as charge transport layer, analysing their potential for improved operation.

Large-scale quantum networks require dynamic and resource-efficient solutions to reduce system complexity with maintained security and performance to support growing number of users over large distances. Current encoding schemes including time-bin, polarization, and orbital angular momentum, suffer from the lack of reconfigurability and thus scalability issues. Here, we demonstrate the first-time implementation of frequency-bin-encoded entanglement-based quantum key distribution and a reconfigurable distribution of entanglement using frequency-bin encoding.

Structural and photoelectric properties of p-i-n photodiodes based on GeSiSn/Si multiple quantum dots both on Si and silicon-on-insulator (SOI) substrates were investigated. Elastic strained state of grown films was demonstrated by x-ray diffractometry. Annealing of p-i-n structures before the mesa fabrication can improve the ideality factor of current-voltage characteristics.
