Ga2O3 nanomaterials synthesized from ball-milled GaN powders

Study of Ga2O3Nanobelts Synthesized by the Thermal Annealing of GaN Powders

“…The growth of Ga 2 O 3 nanobelts may take place in a sequence of steps that includes the reaction of Ga from the GaN powders with oxygen. Although we have used a N 2 atmosphere in the furnace, we believe that the oxygen in the Ga 2 O 3 has come from the air leakage, or the residual oxygen in the furnace, consistent with the assertion made by Lee et al [11].…”

One-dimensional nanomaterials synthesized using high-energy ball milling and annealing process

“…Same effect of nanowire yield improvement has also been observed in GaN nanowires [44]. In addition, because of the lower vaporization or reaction temperature, many nanowires such as SnO 2 , Ga 2 O 3 , and GaN can be successfully produced from the milled precursors while only polycrystalline nanocrystals are formed without HEBM treatment [44][45][46]. Another effect of mechanical activation is the formation of well-crystallized structures in nanowires and nanotubes.…”

Metal Oxide-Based Nanostructures

“…At present nanobelts are available for practically all basic oxides used in chemical sensors and there is plenty of information about the synthesis of nanobelts based on SnO 2 , In 2 O 3 , ZnO, Ga 2 O 3 , TiO 2 , etc. (Li et al 2000 ;Pan et al 2001 ;Dai et al 2002 ;Lee et al 2002 ;Konga and Wang 2003 ;Varghese et al 2003a, b ;Jung et al 2003 ;Kong et al 2003 ;Guha et al 2004 ) . Synthesis of nanobelts can be accomplished using various methods (Liu et al 2001 ;Wang et al 2002 ;Li et al 2002 ;Xu et al 2002 ) , creating good conditions for widening research into such nanosize materials.…”
