Organic photoconductive materials

Interfacial engineering of organic nanofibril heterojunctions into highly photoconductive materials.

Photoconductive organic materials have gained increasing interest in various optoelectronics, such as sensors, photodetectors, and photovoltaics. However, the availability of such materials is very limited due to their intrinsic low charge carrier density and mobility. Here, we present a simple approach based on nanofibril heterojunction to achieve high photoconductivity with fast photoresponse...

Photoconductive terahertz generation from textured semiconductor materials

Photoconductive (PC) terahertz (THz) emitters are often limited by ohmic loss and Joule heating-as these effects can lead to thermal runaway and premature device breakdown. To address this, the proposed work introduces PC THz emitters based on textured InP materials. The enhanced surface recombination and decreased charge-carrier lifetimes of the textured InP materials reduce residual photocurr...

Photoconductive Properties of Novel High- Performance Organic Semiconductors

Photophysical and photoconductive properties of organic semiconductor composites

We report on the effects of introducing guest molecules into a functionalized anthradithiophene (ADT) host on the photoluminescent (PL) and photoconductive properties of solution-deposited thin films. An addition of 0.1 wt % of an ADT derivative with cyano end groups (ADT-TIPS-CN) to a fluorinated ADT derivative (ADT-TES-F) resulted in the near complete quenching of the fluorescence spectrum of...

Metal-organic framework materials as nano photocatalyst

Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...
