چکیده

Cd(2+) causes deep traps on the surface of CdTe quantum dots (QDs) often leading to a long response time for a photodetector. Poly(3-hexylthiophene) (P3HT) can be used to selectively passivate the Cd(2+) -related deep traps by forming a Cd-S bond, while maintaining the shallow traps. By tailoring the trap depth of the CdTe QDs, a high gain, fast response, and low noise P3HT:CdTe nanocomposite photodetector is achieved.

Single-crystalline CdTe nanowire field effect transistors as nanowire-based photodetector.

The electronic and photoconductive characteristics of CdTe nanowire-based field effect transistors were studied systematically. The electrical characterization of a single CdTe nanowire FET verifies p-type behavior. The CdTe NW FETs respond to visible-near infrared (400-800 nm) incident light with a fast, reversible and stable response characterized by a high responsivity (81 A W(-1)), photocon...

Large Gain, Low Noise Nanocomposite Ultraviolet Photodetectors with a Linear Dynamic Range of 120 dB

reduced dark current enabled a constant responsivity from light intensity of 10 −2 Wcm −2 all the way down to 12 pWcm −2 , resulting in a very large linear dynamic range of 90 dB. [ 5 ] However, the insertion of 25 nm C-TPD between PEDOT:PSS and C 60 interface also blocked the tunneling of electrons (secondary electron injection) into C 60 even under large reverse bias of –6 V, and thus annulle...

Low Noise, High Detectivity Photodetectors based on Organic Materials

Organic photodetectors (OPDs) are potentially useful in many applications because of their light weight, flexibility and good form factors. Despite the high detectivities that have been frequently reported for OPDs recently, the application of these OPDs for weak light detection has been rarely demonstrated. In this thesis, low noise, high gain photodetectors based on organic and ZnO nanopartic...

A nanocomposite ultraviolet photodetector based on interfacial trap-controlled charge injection.

Ultraviolet photodetectors have applications in fields such as medicine, communications and defence, and are typically made from single-crystalline silicon, silicon carbide or gallium nitride p-n junction photodiodes. However, such inorganic photodetectors are unsuitable for certain applications because of their high cost and low responsivity (<0.2 A W(-1)). Solution-processed photodetectors ba...
