Local manipulation of the defect structures in 2D semiconducting transition metal dichalcogenide (2D TMD) opens rich research avenues harnessing their unique optoelectronic properties, where reliable structure formation methods are highly desirable. Here, concept optical soldering (OS) on few-layer MoS2 to form site-selective with induced photoluminescence (PL) is proposed and demonstrated. OS ...

We demonstrate a new type of Au{111} substrate that is both atomically flat and optically transparent, which consists of solution-grown flat gold nanoparticles (FGNPs) deposited on indium tin oxide (ITO)-coated glass. We show that FGNPs are atomically flat single-crystal plates with large {111} faces that expose only 2-4 atomic layers. These FGNPs are excellent platforms for alkanethiol self-as...

The electrical transport properties of films derived from aqueous semiconducting nanoparticle are fully described by a phenomenological model that relates intrinsic film morphology to photovoltaic response. The model is applied to a new bulk heterojunction blend, composed of organic semiconducting nanoparticles formed from the polymer donor poly[{2,6-(4,8-didodecylbenzo[1,2-b:4,5-b']dithiophene...

In this study a sensitive electrochemical sensor for the detection of E.coli has been developed using silver nanoparticle (Ag) embedded poly(9,9-dioctylfluorene-ran-phenylene) (CFP) nanocomposite as a conductive platform and DNA hybridization technique. The new polymer was synthesized from 9,9-dioctylfluorene and 1,3-dichlorobenzene and biphenyl through Friedel Crafts alkylation reacti...

Structural, electrical and optical properties of indium tin oxide or ITO (In2O3:SnO2) thin films on different substrates are investigated. A 100-nm-thick pre-deposited zinc oxide (ZnO) buffer layer is utilized to simultaneously improve the electrical and optical properties of ITO films. High purity ZnO and ITO layers are deposited with a radio frequency sputtering in argon ambient with plasma p...

We report an indium tin oxide (ITO) free inverted organic solar cell with alternate aluminium doped zinc (AZO) front cathode layer based on the consideration of blocking harmful ultraviolet (UV) rays, which is one prominent reasons for degradation cells. To further enhance power conversion efficiency AZO/ZnO/PTB7:PC71BM/MoO3/Ag cell, plasmonic gold nanoflowers were embedded inside active layer....
