Carrier Transport in Self-Organized Oligosilane Thin Films: Controllable Mobility by Terminal Alkyl- Chains of Different Length

Carrier transport properties of self-organized oligosilanes with different lengths of terminal alkyl-chains were investigated by the time-of-flight transient photocurrent technique. The self-organized oligosilane thin films possess a high molecular order, which generates well-ordered carrier hopping...

More Information
Summary:Carrier transport properties of self-organized oligosilanes with different lengths of terminal alkyl-chains were investigated by the time-of-flight transient photocurrent technique. The self-organized oligosilane thin films possess a high molecular order, which generates well-ordered carrier hopping sites. The order of the hopping sites enables us to control hopping distance by the terminal chains, resulting in systematic change of the carrier mobility.
