We describe measurements of the terahertz dielectric properties of normal alkanes. We study all of the liquid alkanes from pentane (C5) to hexadecane (C16) over the temperature range from 20–80°C, and obtain the absorption coefficients and refract

We describe the observation of a broad and strongly temperature-dependent peak in the terahertz absorption spectrum of several linear n-alkanes. On cooling from the liquid into the rotator phase, the absorption is enhanced within a very narrow temper

We investigate the feasibility of using terahertz imaging to quantify the relative dodecane (C 12 H 26 ) content and long-term stability of dodecane-surfactant-brine emulsions of varying salinity for their use in surfactant-enhanced oil recovery.

We characterize the phase behavior of linear n-alkanes with n > 22, using terahertz spectroscopy. We observe enhanced absorption in the quasi-ordered rotator phase, the first report of disorder-induced THz absorption in a rotator crystal.

We present results from our investigation into the liquid-lattice structures of n-pentane (C 5 H 12 ) through n-hexadecane (C 16 H 34 ). We observe alternating absorption values, at single frequencies, which are surprising and provide information abo

We observe terahertz vibrational modes in crystals of n-octadecane, a non-hydrogen-bonding, non-polar molecule. These modes are not present in amorphous samples.

We demonstrate surface field generation of terahertz radiation from p-InMnAs. The influence of an applied magnetic field and the sample temperature on the generated terahertz field is examined.

We have studied the terahertz radiation emitted by the dilute magnetic semiconductor InMnAs under femtosecond laser illumination, as a function of temperature. We observe a reversal of the polarity of the emitted terahertz field as the temperature is

We investigate the photoconductivity of regioregular poly(3-hexylthiophene) using 400 and 800 nm light. We observe a linear dependence of the photocurrent on optical power at both wavelengths.
