We report direct evidence for dissociative adsorption and recombinative desorption of triethylgallium on GaAs(100). Deuterated and undeuterated triethylgallium were used to investigate two distinct ethyl species produced by chemisorption of triethylg

Knowledge of the observable properties of orbital debris is necessary to validate debris models for both the low Earth orbit (LEO) and the geosynchronous Earth orbit (GEO). Current methods determine the size and mass of orbital debris based on knowle

Three monomeric, base-free tris(primary amido) compounds of the type E[N(H)Mes*](3) (1, E = Al; 2, E = Ga; 3, E = In; Mes* = 2,4,6-tri-tert-butylphenyl) have been synthesized via the salt elimination reaction of Mes*N-(H)Li with ECl3. The singly base

Decomposition of the surface ethyl group formed by dissociative adsorption of triethylgallium (TEGa) on GaAs(100) is investigated using temperature programmed desorption. Deuterium labeling indicates that decomposition of the surface ethyl group proc

Two lithium compounds of the substituted fluorenyl ligand 9-[2-(dimethylamino)ethyl]fluorenyl (FlN) have been prepared and isolated. The X-ray crystal structures of FlNLi·Et2O (2) and FlNLi·2THF (3) have been obtained. In 2 the lithium atom is coor

Over the past several years, the interest in orbital debris has grown because of the hazard it poses to operating satellites. Models of the debris environment depend on accurate assessments of the masses and sizes of debris particles. Utilizing data

Oxidation of [FeCp*(η1-dtc)(CO)2], 1 (Cp* = η5-C5Me5, dtc = S2CNMe2), or [FeCp*(η2-dtc)(CO)], 2, using [FeIIICp2]+X- (X- = PF6- or BF4-, Cp = η5-C5H5) in THF cleanly gives [FeIIICp*(η2-dtc)(CO)]+X-, 2+X-, as microcrystalline green, thermally sta
