We describe the use of stimulated Raman pumping in a molecular beam to perform quantum state resolved gas-surface reactivity measurements for molecules prepared in totally symmetric vibrational states. Vibrational states of homonuclear diatomics as well as ...
In this work, I present the results of my studies on the state-resolved reactivity of silane (SiH4) on the Si(100)-(2x1) surface. The results demonstrate a co-existence of both a direct and a precursor mediated mechanisms for the dissociative chemisorption ...
Photonic crystal (PC) cavities enable localization of light into volumes (V) below a cubic optical wavelength (smaller than any other types of optical resonators) with high quality (Q) factors [1]. This permits a strong interaction of light and matter, whi ...
We present a study of the C-H and C-N vibrational modes of acetonitrile molecules at the interface between the bulk liquid and a gold film using both time and frequency domain femtosecond sum frequency generation. Acetonitrile is adsorbed on the gold surfa ...
Self-assembled quantum-dots (QDs) represent a distributed ensemble of zero dimensional structures with a near-singular density of states. Implemented as the active medium in a diode laser their unique properties lead to improved and often novel characteris ...
The quantum state-resolved reactivity S0 of SiH4 on Si(100)-2x1 has been measured for the first time for two vibrationally excited Si-H stretch local mode states (|2000> and |1100>) as well the ground state S0 as a function of translational energy En and s ...
H2S adsorption and dissociation on the gallium-rich GaAs( 001)- 4 x 2 surface is investigated using hybrid density functional theory. Starting from chemisorbed H2S on the GaAs( 001)- 4 x 2 surface, two possible reaction routes have been proposed. We find t ...
We present a combined experimental and theoretical study of the CO2 interaction with the Ni(110) surface. Photoelectron spectroscopy, temperature-programmed desorption, and high-resolution electron energy loss spectroscopy measurements are performed at dif ...
Laser light is an invaluable tool for detailed experimental studies of chemical reactions. The ability to prepare reagent molecules in specific quantum states and to resolve the quantum state distribution of reaction products using laser radiation has been ...
A photoacoustic sensor has been developed for trace-gas monitoring using a near-infrared semiconductor laser emitting in the 2ν3 band of methane at 1.65 μm. The apparatus was designed for on-line process control in the manufacturing of the novel low-water- ...
