The dynamic characteristics of the ions emitted from ultrashort laser interaction with materials were studied. A series of successive experiments were conducted for six different elements (C, Al, Cu, Mo, Gd, and W) using 40 fs, 800 nm Ti: Sapphire laser. Time-of-flight (TOF) ion profile was analyzed and charge emission dependencies were investigated. The effects of incident laser interaction wi...

The molecular anions, Li(3)O(-) and Na(3)O(-) were produced by laser vaporization and studied via anion photoelectron spectroscopy. Li(3)O(-) and Na(3)O(-) are the negative ions of the super-alkali neutral molecules, Li(3)O and Na(3)O. A two-photon process involving the photodetachment of electrons from the Li(3)O(-) and Na(3)O(-) anions and the photoionization of electrons from the resulting L...

LiNi0.4Co0.3Mn0.3O2 thin film electrodes are fabricated from LiNi0.4Co0.3Mn0.3O2 raw powder at room temperature without pretreatments using aerosol deposition that is much faster and easier than conventional methods such as vaporization, pulsed laser deposition, and sputtering. The LiNi0.4Co0.3Mn0.3O2 thin film is composed of fine grains maintaining the crystal structure of the LiNi0.4Co0.3Mn0....

We report the observation of two Fe-doped boron clusters with wheel-type structures, containing an octa-coordinate (C8v-Fe B8 ) and a nona-coordinate (D9h-Fe B9 ) Fe atom. The clusters were produced in a laser vaporization supersonic molecular beam and characterized by combined photoelectron spectroscopy and ab initio studies. Chemical bonding analyses revealed that in the ground state both clu...

Carbenes of platinum and palladium, PtC3 and PdC3, were generated in the gas phase through laser vaporization of a metal target in the presence of a low concentration of a hydrocarbon precursor undergoing supersonic expansion. Rotational spectroscopy and ab initio calculations confirm that both molecules are linear. The geometry of PtC3 was accurately determined by fitting to the experimental m...

A combination of planar laser imaging and theoretical modeling has been used to examine matrix-assisted pulsed-laser evaporation direct write MAPLE-DW in the bubble regime. MAPLE-DW is a method for patterning substrates via laser-initiated forward transfer of an organic fluid containing metallic particles and coated on a transparent support. For our conditions, best deposition of a silver-based...

Possible isomers of the gallium arsenide clusters of the formula Ga,,As, containing up to ten atoms and icosahedral clusters are enumerated. The possible parent polyhedrons up to ten vertices are constructed and then Pdlya’s theorem is applied to each polyhedron to calculate the generating functions for the enumeration of the isomers of gallium arsenide clusters of the formula Ga,,,As,. The dis...
