Nanocrystalline Cu2O prepared under high pressures

Influence of target power on properties of CuxO thin films prepared by reactive radio frequency magnetron sputtering

“…4, D p obtained from the Cu 2 O (111) peak is depicted and exhibits an increase from 10 to 30 nm with increasing P tar . Similarly, D p from the Cu 2 O (200) peak increases from 14 to 20 nm as P tar is increased from 160 to 190 W. Ponyatovskii et al [19] studied the effect of high external pressure on the structure of Cu 2 O and revealed a phase transition to CuO accompanied by a decrease in grain size. Machon et al [20] also obtained similar results and attributed these effects under high pressure to a considerable increase in the microstrain within the film.…”

Morphologically controlled synthesis of Cu2O nanocrystals and their properties

“…The electrical properties of individual Cu 2 O nanowires synthesized under hydrothermal conditions in the presence of poly (2,5-dimethoxyanaline) have also been examined [14]. A solar cell consisted of vertically oriented n-type ZnO nanowires, surrounded by a film constructed from p-type Cu 2 O nanoparticles has recently been fabri- [8,14,[50][51][52][53][54][55][56][57] Sputtering Sphere [58] High pressure treatment Sphere [59] Irradiation Octahedron Cube Cube [60,61] * RD: rhombic dodecahedron.…”

Fabrication and microstructure of Cu2O nanocubes

“…Different shapes of Cu 2 O nanoparticles have been synthesized by various methods [8][9][10]. However, no detailed investigation on the microstructure and growth mechanism of the Cu 2 O nanocubes has been reported.…”
