Frequency response analysis of pentacene thin-film transistors with low impedance contact by interface molecular doping
Frequency response measurements were performed on top-contact pentacene organic thin-film transistors (OTFTs). The ac characteristics of OTFTs are strongly limited by the contact interface between a… Expand
Simple and scalable gel-based separation of metallic and semiconducting carbon nanotubes.
We report a rapid and scalable method for the separation of metallic and semiconducting single-wall carbon nanotubes (SWCNTs); the separation is performed by the selective adsorption of… Expand
Degradation mechanism of CH3NH3PbI3 perovskite materials upon exposure to humid air
Low stability of organic-inorganic perovskite (CH3NH3PbI3) solar cells in humid air environments is a serious drawback which could limit practical application of this material severely. In this… Expand
Analysis of charge transport in a polycrystalline pentacene thin film transistor by temperature and gate bias dependent mobility and conductance
The gate bias and temperature dependent field-effect mobility and conductance of a polycrystalline pentacene thin film transistor (TFT) were analyzed to study the charge transport in the material.… Expand
Charge injection process in organic field-effect transistors
The charge injection process in top-contact organic field-effect transistors was energetically observed with displacement of the Fermi level as a result of scanning the gate voltage. Doping of… Expand
Glancing angle deposition of copper iodide nanocrystals for efficient organic photovoltaics.
We report a simple method to achieve efficient nanostructured organic photovoltaics via patterning copper iodide (CuI) nanocrystals on indium tin oxide by glancing angle deposition. The strong… Expand
Phase separation of co-evaporated ZnPc:C60 blend film for highly efficient organic photovoltaics
We demonstrate phase separation of co-evaporated zinc phthalocyanine (ZnPc) and fullerene (C60) for efficient organic photovoltaic cells. With introducing a… Expand
Universal rules for visible-light absorption in hybrid perovskite materials
A variety of organic-inorganic hybrid perovskites (APbX3) consisting of mixed center cations [A = CH3NH3+, HC(NH2)2+, and Cs+] with different PbX3− cages (X = I, Br, and Cl) have been developed to… Expand

A strategy to control the molecular growth of coevaporated zinc phthalocyanine (ZnPc) and fullerene (C60) blended films for efficient organic photovoltaic (OPV) cells was demonstrated. Introduction… Expand
Methyl-terminated Si(1 1 1) surface as the ultra thin protection layer to fabricate position-controlled alkyl SAMs by using atomic force microscope anodic oxidation
Abstract Methyl-terminated Si(1 1 1) (Me–Si(1 1 1)) and bilayer-GaSe terminated Si (BGS) surfaces were investigated to explore their usefulness as the protection layer in the fabrication process of… Expand
