NIR Schottky photodetectors based on individual single-crystalline GeSe nanosheet.
We have synthesized high-quality, micrometer-sized, single-crystal GeSe nanosheets using vapor transport and deposition techniques. Photoresponse is investigated based on mechanically exfoliated GeSe nanosheet combined with Au contacts under a global laser irradiation scheme. The nonlinearship, asymmetric, and unsaturated characteristics of the I-V curves reveal that two uneven back-to-back Sch...
متن کاملDirect Observation of High Photoresponsivity in Pure Graphene Photodetectors
Ultrafast and broad spectral bandwidth photodetectors are desirable attributable to their unique bandstructures. Photodetectors based on graphene have great potential due to graphene's outstanding optical and electrical properties. However, the highest reported values of the photoresponsivity of pure graphene are less than 10 mA/W at room temperature, which significantly limits its potential a...
متن کاملGraphene-ruthenium complex hybrid photodetectors with ultrahigh photoresponsivity.
The maximum responsivity of a pure monolayer graphene-based photodetector is currently less than 10 mA W(-1) because of small optical absorption and short recombination lifetime. Here, a graphene hybrid photodetector functionalized with a photoactive ruthenium complex that shows an ultrahigh responsivity of ≈1 × 10(5) A W(-1) and a photoconductive gain of ≈3 × 10(6) under incident optical inten...
متن کاملStrong enhancement of photoresponsivity with shrinking the electrodes spacing in few layer GaSe photodetectors
A critical challenge for the integration of optoelectronics is that photodetectors have relatively poor sensitivities at the nanometer scale. Generally, a large electrodes spacing in photodetectors is required to absorb sufficient light to maintain high photoresponsivity and reduce the dark current. However, this will limit the optoelectronic integration density. Through spatially resolved phot...
متن کاملLowdimensional Additive Overlapping Clustering
To reveal the structure underlying two-way two-mode object by variable data, Mirkin (1987) has proposed an additive overlapping clustering model. This model implies an overlapping clustering of the objects and a reconstruction of the data, with the reconstructed variable profile of an object being a summation of the variable profiles of the clusters it belongs to. Grasping the additive (overlap...
