We propose a novel method to enhance the THz emission from CuxO/metal nano thin film by using columnar-structured microsized porous silicon (MS-PSi) as the substrate. THz emission was improved seve...

Using terahertz (THz) time-domain spectroscopy, we have measured the complex permittivity of 14 monohydric alcohols in the frequency range 0.2–2.5 THz, at temperatures ranging from 253 to 323 K. The molecular structures of these monohydric alcohols

Complex permittivity measurements of a series of normal alcohols (methanol, ethanol, 1-propanol, 1-butanol, and 1-pentanol) are performed by THz time-domain spectroscopy in the frequency range of 0.2–2.5 THz at temperatures of 253–323 K. It is fo

Using terahertz (THz) time-domain spectroscopy, we measured the complex permittivity of some normal (1-propanol, 1-butanol, and 1-pentanol) and secondary alcohols (2-propanol, 2-butanol, and 2-pentanol) in the frequency ranges from 0.2 to 2.5 THz at

Using terahertz (THz) time-domain spectroscopy, we have measured the complex permittivity of seven pentanol isomers (1-pentanol, 2-pentanol, 3-pentanol, 2-methly-1-butanol, 3-methyl-1-butanol, 2-methyl-2-butanol, and 3-methyl-2-butanol) in the freque

Time resolved photoluminescence (PL) measurements at low temperature are performed on colloidal ZnO nanocrystals dispersed in t-butanol. Considering the particle size dependence of the decay times we conclude that the luminescence is composed of two

Raman spectra of liquid carbon disulfide (CS2) were measured under high pressures and in dilution with ethanol and with heptane. The pressure and concentration dependences of the molecular vibration modes ν1 and 2ν2 of CS2 are discussed. The interm

We have observed coherent phonons and electronic response in bismuth single crystals under hydrostatic pressure up to 3 GPa at room temperature. Both signals show drastic changes at 2.5 GPa where phase transition occurs. The phonon frequency decrease

We have studied the coherent longitudinal acoustic (LA) phonon in a single crystal of pyrite (FeS2) by femtosecond pump and probe spectroscopy. The coherent LA phonon signal is observed as a very clear oscillatory structure in the reflection type pum

The optical heterodyne spectroscopy of optical Kerr effect (OKE) in liquid carbon disulfide (CS2) was performed under various high pressures using a diamond anvil cell (DAC). The relaxation time of orientation was determined up to 1.20 GPa at 295 K u
