Kinetic profile of adsorption and self-assembling of thiophene oligomers studied by optical second harmonic generation
The process of self-assembling of thiophene oligomers on gold substrate was studied in situ by optical second harmonic generation (SHG). It is shown that for thiophene both molecular andExpand

Enhanced terahertz emission from strain-induced InGaAs/InAlAs superlattices
We propose, fabricate, and evaluate strain-induced InGaAs/InAlAs superlattice (SL), which can efficiently radiate broadband terahertz (THz) waves. By means of optical pump-probe measurements, weExpand
