    Monodisperse Colloidal Gallium Nanoparticles: Synthesis, Low Temperature Crystallization, Surface Plasmon Resonance and Li-Ion Storage
    摘要:
    We report a facile colloidal synthesis of gallium (Ga) nanoparticles with the mean size tunable in the range of 12-46 nm and with excellent size distribution as small as 7-8%. When stored under ambient conditions, Ga nanoparticles remain stable for months due to the formation of native and passivating Ga-oxide layer (2-3 nm). The mechanism of Ga nanoparticles formation is elucidated using nuclear magnetic resonance spectroscopy and with molecular dynamics simulations. Size-dependent crystallization and melting of Ga nanoparticles in the temperature range of 98-298 K are studied with X-ray powder diffraction, specific heat measurements, transmission electron microscopy, and X-ray absorption spectroscopy. The results point to delta (δ)-Ga polymorph as a single low-temperature phase, while phase transition is characterized by the large hysteresis and by the large undercooling of crystallization and melting points down to 140-145 and 240-250 K, respectively. We have observed size-tunable plasmon resonance in the ultraviolet and visible spectral regions. We also report stable operation of Ga nanoparticles as anode material for Li-ion batteries with storage capacities of 600 mAh g(-1), 50% higher than those achieved for bulk Ga under identical testing conditions.

    通过原子层沉积使用Ga(NMe2)3和NH3等离子体的外延GaN
    摘要:
    高质量外延GaN的低温沉积对其在电子应用中的集成至关重要。使用具有AlN缓冲层或氮化蓝宝石作为衬底的SiC,在大约800°C的化学气相沉积法可促进GaN的生长。在这里,我们介绍了使用三(二甲基氨基)镓(III)和NH 3的低温原子层沉积(ALD)工艺等离子体。ALD过程显示出在130–250°C之间的自限制行为,每个周期的增长率为1.4Å。所产生的GaN膜在所有沉积温度下均在Si(100)上结晶,具有接近化学计量的Ga / N比,且碳和氧杂质低。当将GaN沉积在4H-SiC上时,不需要AlN缓冲层即可外延生长膜,这是以前从未报道过的。测得GaN膜的带隙约为3.42 eV,费米能级表明GaN是无意地被n型掺杂的。这项研究表明了ALD在GaN基电子器件中的潜力。

Based on the present study, salen ligands with limited steric hindrance and a certain degree of flexibility appear best suited for iso-selective ROP by (salen)Ga chelates.

    The insertion of carbodiimides into existing metal-heteroatom bonds is an important preparative route for the synthesis of useful ligand systems such as amidinates and guanidinates. Our interest lies in multiple insertions at one metal center and the mechanisms of insertion and rearrangement. We have synthesized and characterized [Me(2)NC(N(i)Pr)(2)](n)M(NMe(2))(3)(-)(n) (n = 1, 2, 3; M = Al, Ga).

Compound 2 effectively catalyzes the hydroamination of terminal alkynes (such as 1-hexyne and phenylacetylene) in the presence of primary amines (aniline and butylamine).

    Thin films of Ga2O3 have been produced from [Ga(NMe2)3]2 and ROH (R = CH2CH2NMe2, CH(CH2NMe2)2, CH(CH3)CH2NMe2, CH2CH2OMe and C(CH3)2CH2OMe) by aerosol assisted chemical vapour deposition on glass. Transparent, unreflective films were obtained at a deposition temperature of 550 °C using toluene as solvent. The gallium oxide films were analyzed by Scanning electron microscopy (SEM), Raman spectroscopy, wavelength dispersive analysis of X-rays (WDX) and X-ray photoelectron spectroscopy (XPS). The gallium oxide films obtained were X-ray amorphous. Gas-sensing experiments indicated that the films showed an n-type response to ethanol at a variety of temperatures.
