Journal ArticleDOI
Infrared Photodetectors Based on CVD-Grown Graphene and PbS Quantum Dots with Ultrahigh Responsivity
TL;DR: Infrared photodetectors based on single-layer CVD-grown graphene and PbS quantum dots, which are fabricated by solution processing, show ultrahigh responsivities of up to 10(7) A/W under infrared light illumination.
Journal ArticleDOI
Graphene and graphene-like two-dimensional materials in photodetection: mechanisms and methodology.
TL;DR: The recent progress in photodetection based on graphene and graphene-like 2D materials is reviewed and the summary of some most important physical mechanisms, including photoelectric, photo-thermoelectric, and photo-bolometric regimes are started.
Journal ArticleDOI

TL;DR: This work uses ultrafast 2D vibrational spectroscopy of methylammonium (MA) lead iodide to directly resolve the rotation of the organic cations within the MAPbI3 lattice and reveals two characteristic time constants of motion.
Journal ArticleDOI
The application of highly doped single-layer graphene as the top electrodes of semitransparent organic solar cells.
TL;DR: A single-layer graphene film with high conductance and transparency was realized by effective chemical doping and all of the devices showed higher efficiency from the graphene than ITO side, which was attributed to the better transmittance of the graphene electrodes.
Journal ArticleDOI
A highly sensitive ultraviolet sensor based on a facile in situ solution-grown ZnO nanorod/graphene heterostructure
TL;DR: By combining the attributes of photosensitive ZnO nanorods and highly conductive graphene, this work demonstrates a highly sensitive visible-blind ultraviolet (UV) sensor based on graphene related heterostructure for the first time.
