Measurement of complex Χ(3) using degenerate four-wave mixing with an imaged 2-D phase grating
(Georgia Institute of Technology, 2006-09)
We present a simple optical arrangement for phase sensitive detection of degenerate four-wave mixing (DFWM) to characterize the real and imaginary parts of c(3) using an imaged 2-D phase grating. Phase sensitive coherent ...
Solution-processible high-permittivity nanocomposite gate insulators for organic field-effect transistors
(Georgia Institute of Technology, 2008-07-07)
We report on solution-processible high permittivity nanocomposite gate insulators based on BaTiO₃ nanoparticles, surface-modified with a phosphonic acid, in poly(4-vinylphenol) for organic field-effect transistors. The use ...
Materials for multiphoton 3D microfabrication
(Georgia Institute of Technology, 2007-07)
Two-photon/multiphoton lithography (MPL) has emerged as a versatile technique for the fabrication of complex 3D polymeric, hybrid organic/inorganic, and metallic structures. This article reviews some recent advances in the ...
65 nm feature sizes using visible wavelength 3-D multiphoton lithography
(Georgia Institute of Technology, 2007-03)
Nanoscale features as small as 65 ± 5 nm have been formed reproducibly by using 520 nm femtosecond pulsed excitation of a 4,4'- bis(di-n-butylamino)biphenyl chromophore to initiate crosslinking in a triacrylate blend. ...
