Employing liquid crystal material as regulator to enhance performance of photomultiplication type polymer photodetectors

Kaixuan Yang et al.

Summary: Photomultiplication type polymer photodetectors were fabricated using PBDB-T:BTPV-4F and PBDB-T:BTR:BTPV-4F as blend active layers, achieving improved performance by controlling electron traps and hole tunneling in the blend active layers. The use of the regulator BTR optimized hole mobility in the blend active layers, leading to enhanced responsivity and external quantum efficiency of the PM-PPDs.

Defect effect on the performance of nonpolar GaN-based ultraviolet photodetectors

Yuhui Yang et al.

Summary: The anisotropy of GaN(11-20) enables the fabrication of polarized ultraviolet photodetectors for various applications. This study investigated how different defect densities, such as screw or mixed dislocations, edge dislocations, and basal stacking faults, affect the performance of GaN(11-20)-based PDs, impacting dark current, responsivity, and response time. The results showed that screw or mixed dislocations increase dark current, while edge dislocations and basal stacking faults decrease responsivity, and all three types of defects increase response time by creating traps for carrier recombination.

Impact of crystallinity towards the performance of semi-polar (11-22) GaN UV photodetector

Abdullah Haaziq Ahmad Makinudin et al.

Summary: High crystal quality semi-polar (11-22) GaN-based UV photodetectors exhibit significantly different photo-responses and dark currents depending on the crystal quality. Integration of high crystalline structure with metal-semiconductor-metal type photodetectors results in reduced dark current and significantly enhanced responsivity values. The photo-response time of detectors with enhanced crystal epilayer is measured to be as low as 170 ms with the fastest recovery time reported in semi-polar (11-22) GaN metal-semiconductor-metal UV photodetectors.

Highly Sensitive Narrowband Photomultiplication-Type Organic Photodetectors Prepared by Transfer-Printed Technology

Zijin Zhao et al.

Summary: Narrowband photomultiplication-type organic photodetectors (PMOPDs) were developed using poly(3-hexylthiophene-2,5-diyl) (P3HT) as the optical field adjusting (OFA) layer and transfer-printed P3HT:[6,6]-phenyl-C-71-butyric acid methyl ester (PC71BM) as the photomultiplication (PM) layer. The addition of a wide bandgap polymer poly[N,N'-bis(4-butylphenyl)-N,N'-bis(phenyl)benzidine] (P-TPD) into the OFA layer significantly enhanced the device performance, with improved hole tunneling injection and transport efficiency attributed to increased trapped electron density near the Al electrode and improved hole mobility. The promising potential of PMOPDs in imaging applications was demonstrated through clear imaging without the need for current preamplifiers.

Highly sensitive, broad-band organic photomultiplication-type photodetectors covering UV-Vis-NIR

Ming Liu et al.

Summary: UV-Vis-NIR broad-band organic photomultiplication-type photodetectors were successfully fabricated with double-layered thin active layers, achieving high efficiency photodetection and a broad spectral response range from 300 to 1000 nm. The devices demonstrated the highest external quantum efficiency values, as well as maximum specific detectivity and linear dynamic range among organic photodetectors under the same applied voltage conditions.
