title: Coaxial organic p-n heterojunction nanowire arrays: one-step synthesis and photoelectric properties.
abstract: Organic/organic single-crystal coaxial p-n heterojunction nanowire arrays consisting of p-type copper phthalocyanine (CuPc) and n-type 5,10,15,20-tetra(4-pyridyl)-porphyrin (H(2)TPyP) are fabricated through a one-step physical vapor transport (PVT) process. Each single junction wire revealed high photodependent rectifying and sensitive photoresponsive characteristics in devices of light-controlled diodes and photoswitches. The typical photovoltaic device based on a single p-n junction exhibited a high open-circuit voltage (Voc) of 0.64 V.
