Abstract:

In this study, we investigate the bulk effect of photoresponsive gate insulators on the photoresponse of organic phototransistors (OPTs), using OPTs with poly(4-vinylphenol) layers of two different thicknesses. For the photoresponse, the interplay between the charge accumulation (capacitance) and light-absorbance capabilities of a photoresponsive gate insulator was investigated. Although an OPT with a thicker gate insulator exhibits a lower capacitance and hence a lower accumulation capability of photogenerating charges, a thicker poly(4-vinylphenol) layer, in contrast to a thinner one, absorb

Abstract:

We have examined the role of Ca++ in phototransduction by manipulating the intracellular Ca++ concentration in physiologically active suspensions of isolated and purified rod photoreceptors (OS-IS). The results are summarized by the following. Measurement of Ca++ content using arsenazo III spectroscopy demonstrates that incubation of OS-IS in 10 nM Ca++-Ringer's solution containing the Ca++ ionophore A23187 reduces their Ca++ content by 93%, from 1.3 to 0.1 mol Ca++/mol rhodopsin. Virtually the same reduction can be accomplished in 10 nM Ca++-Ringer's without ionophore, presumably via the plas

The direct photoresponse of Es-1 had a peak at 580 nm, while A-P-l had its peak at 490nm. Under normal conditions, Es-1 was hyperpolarized by blue-green light (490nm) and was depolarized by yellow light (580n

Abstract:

Silicon is a long-standing photosensitive material because of its unique photoelectronic properties and mature manufacturing technology. However, silicon photodetectors are generally limited by weak photoresponse in the near-infrared region. In this work, pressure is used as an effective means of tuning the photoresponse of silicon, specifically in the near-infrared region. Silicon has two different types of photoresponse under pressure. In the pressure range from 1 atm to 10 GPa, huge pressure-enhanced photocurrent is observed under illumination by a xenon lamp and near-infrared light (1064 n

Azobenzene containing liquid crystal elastomers (LCEs) are among of the most prominent photoresponsive polymers due to their fast and reversible response to different light stimuli. To bring new functions into the present framework, novel modifications in bulk material morphology are required. Therefore, we produced azobenzene LCE free-standing films with different porosities. While the porosity provided macroscopic morphological changes, at the same time, it induced modifications in alignment of liquid crystal azobenzene units in the films.

Graphene-metal contact is crucial to fabricate high-performance graphene photodetectors since the external quantum efficiency (EQE) of the photodetector depends on the contact properties, and the influence of the contact properties is particularly dominant in short channel devices for high-speed applications. Moreover, junction properties between the channel graphene and graphene near the contact are also important to analyze the photoresponse because the built-in electric field in the junction determines the EQE of the photodetector.

Despite an increase in dark current after the CuPc covering, we obtained a significant improvement in the photocurrent and photoresponse rate. The photocurrent-to-dark current ratio is nearly doubled and the photoresponse process becomes faster for the ZnO/CuPc heterostructure. Improvements

Abstract:

Doping of the lead telluride and related alloys with the group III impurities results in the appearance of unique physical features of the material, such as persistent photoresponse, enhanced responsive quantum efficiency (up to 100 photoelectrons/incident photon), radiation hardness and many others. We review physical principles of operation of the photodetecting devices based on the group III doped IV–VI including possibilities of fast quenching of the persistent photoresponse, construction of a focal-plane array, new readout technique, and others. Comparison of performance of the state of t

Abstract:

In this work, we report the bidirectional photoresponse of the carbon-based graphdiyne/graphene (GDY/Gr) heterojunction photodetector toward the optical logic gates. The uniform GDY film was facilely grown on the surface of Gr serving as the template. Under mV-level bias, the resultant Au/GDY/Gr/Au devices manifest the bidirectional photoresponse to a broad wavelength range with rapid response time, namely, positive and negative photoresponse under negative and positive bias, respectively. It can be understood from the viewpoint of the divergence and coincidence between in-plane and external p

Abstract:

We report on the spatial uniformity of the photoresponces produced by a quantum dot, optically gated, field-effect transistor (QDOGFET) with photon-number-resolving capabilities. In these devices, a photoresponce is produced when a photon photocharges a quantum dot, altering the current flowing through the transistor. Variation in the photoreponces produced by different quantum dots reduces the photon-number resolution of the QDOGFET. By using an optical scanning microscope (OMS) to spatially resolve the photoresponse and a solid immersion lens (SIL) to enhance the spatial resolution of the OS

Abstract:

AbstractAchieving time‐resolved information encryption is crucial for advanced functional materials but remains a formidable challenge. Photoresponsive supramolecular assemblies have gained attention as promising candidates in this area. This work presents a unique strategy that employs α‐cyanostilbenes to construct photoresponsive assemblies which enable finely regulating fluorescence color and photoresponse kinetics, facilitating effective time‐resolved information encryption. Three α‐cyanostilbenes 1–3 are designed by the combination of electron donor 3,4‐ethoxylene dioxythiophene appended
