Chemical Vapor Deposition of Metal Borides

Chemical vapor deposition of metal borides: 6. The formation of neodymium boride thin film materials from polyhedral boron clusters and metal halides by chemical vapor deposition

“…This phenomenon is apparently similar to the growth of single crystalline NdB 6 rods from polycrystalline LaB 6 . [32] The large NdB 6 cubes in Fig. 3(d) were approximately 15-20 µm across an edge.…”

Field Emission of Electrons from Single LaB6 Nanowires

“…Single-crystalline nanowires were grown on metal substrates with a good yield and a small amount of amorphous boron impurity, similar to the CVD approaches that have also been used to produce LaB 6 whiskers with diameters over 1 lm [21,22,[25][26][27].…”

A Thermodynamic Estimation of the Chemical Vapor Deposition of Some Borides

“…It is known (18) that, during thermal dissociation of B H , a series of higher boranes can be obtained, pentaborane (9), B H , and decaborane (14), B H , being among the most stable. It might be accepted that in a CVD process with the participation of diborane the real boron source would be one of these two compounds (with boiling points of 3333C and 2133C, respectively).…”

“…Data were obtained on the temperature dependence of the change in Gibbs free energy of the reactions MeCl g #2BCl g #5.5H g "MeB #11HCl g [9] MeCl g #2BBr g #5.5H g "MeB #5HCl g #6HBr g [10] MeCl g #B H g "MeB #5HCl g #0.5H…”

“…Recently J. T. Spencer and colleagues proposed some higher boranes as alternative boron precursors in the preparation of Ni B (7), GdB (8), and LaB (9) thin "lms by vacuum copyrolysis of these boranes and the chlorides of the corresponding metals.…”
