Dopant Mapping of Semiconductors with Scanning Electron Microscopy

Compound semiconductor devices, as typified by laser diodes, photo diodes, and high electron mobility transistors, are used for optical communication systems, satellite communications, and cellular base stations to meet a growing demand for large-capacity and high-speed communication systems that play a key role in the infrastructure of modern society. The properties and reliability of semicond...

Benzodicarbomethoxytetrathiafulvalene derivatives as soluble organic semiconductors.

A series of new tetrathiafulvalene (TTF) derivatives bearing dimethoxycarbonyl and phenyl or phthalimidyl groups fused to the TTF core (6 and 15-18) has been synthesized as potential soluble semiconductor materials for organic field-effect transistors (OFETs). The electron-withdrawing substituents lower the energy of the HOMO and LUMO levels and increase the solubility and stability of the semi...

Molecular Organic Semiconductors for Electronic Devices

Benzotrithiophene--a planar, electron-rich building block for organic semiconductors.

Several functionalized benzo[1,2-b:3,4-b':5,6-d'']trithiophenes have been synthesized and characterized. The fully planar and highly electron-rich material shows great promise as the donor constituent in donor-acceptor type copolymers for use in organic electronics. As a proof of concept, a copolymer with the electron acceptor, 2,1,3-benzothiadiazole, has been prepared. Side-chain modifications...
