何涛： Organic Single Crystal FETs – Anisotropy, Polymorphs, Stereoisomers and Intrinsic Potential Defects as well as Insulator-Metal Phase Transition
报告简介
Physical properties of active materials built up from small molecules are dictated by their molecular packing in the solid state. Although lots of effects have been given to understand charge transport in organic devices, many issues/mysteries have been left. Some organic semiconductor materials that appear to be promising in terms of their solid state packing and electronic structure (π–π overlap) do not perform well in commonly employed field effect transport measurements, even in single crystal form, because of the intrinsic/extrinsic disorder.My work is straightforward to explore spatially resolved analytical tools and detect such disorder, so as to reveal superior transport properties in organic single crystal transistors and rebuild the link between performance and structure.
Five topics for this speech: (1) Three-Dimensional Charge Transport; (2) Cl2‑NDI Polymorphs; (3) Impact of 2-Ethylhexyl Stereoisomers on the Electrical Performance; (4) Crystal Step Edges Can Trap Electrons and Trap healing on the Surfaces of n-type Organic Semiconductors; (5) Ion-size Tuning of Charge Accumulation and Insulator-Metal phase transition in C60 Single Crystal EDLTs.
