Environmentally Controlled Charge Carrier Injection Mechanisms of Metal/WS2 Junctions

Carrier dynamics and photodetection in charge injection transistors

We study picosecond carrier transport dynamics induced by 200 fs 1.55 mm optical pulses in charge injection transistor structures. We propose and demonstrate a new optoelectronic method for exploring the interactions of hot majority carriers and cold minority carriers, as well as the optical control of real space transfer in these devices. The minority holes photogenerated in the channel produc...

Charge carrier loss mechanisms in CuInS2/ZnO nanocrystal solar cells.

Heterojunction solar cells based on colloidal nanocrystals (NCs) have shown remarkable improvements in performance in the last decade, but this progress is limited to merely two materials, PbS and PbSe. However, solar cells based on other material systems such as copper-based compounds show lower power conversion efficiencies and much less effort has been made to develop a better understanding ...

Study of charge-carrier injection and transport in organic light-emitting diodes

Charge Injection Devices

|The name "charge injection" describes the operation of a generic class of electronic and optoelectronic multiterminal semiconductor devices, based on the real space transfer of hot carriers over a potential barrier into adjacent and separately contacted layers. Charge injection devices enable the implementation of compact optoelectronic gates endowed with a powerful logic functionality. Keywor...
