“…Nevertheless, until now, it is not well understood the seed layer role on the growth mechanism for ZnO nanorods. Some reports state that by forming layers of textured ZnO films by ALD on a substrate, a seeded surface can be used to fabricate high density vertical nanorod arrays [29,30]. From the results, it is observed that thickness influences the texture of ALD ZnO layer and thus, the crystallographic nature of the seed layer that determines the ulterior nanorod growth type.…”

“…We study the dimensional, morphological, orientation and optical properties of the ZnO nanorods using a hybrid growth method that consists in three steps: i) a textured seed layer obtained by ALD, ii) a thermal treatment for ALD ZnO seed layer and iii) vertical ZnO nanorods growth by hydrothermal method. The reported contributions have considered only two steps [29,30].…”

Vertically arrayed ZnO nanorods were synthesized by a hydrothermal method on homoseed layers deposited using atomic layer deposition (ALD) and heat-treated at various temperatures ranging from 200 to 600 °C in air. The effect of the annealing temperatures on nanorod formation was investigated. With increasing temperature, the microstructure of the ZnO seed layers changed from nanocrystals to coarse polycrystals with a preferred orientation, which led to an increase in the length and diameter of the solvothermally Atomic layer depositionZnO Nanorods Thermal treatments

“…Therefore, CdSe has become one of the most promising semiconducting materials. Recently, many experimental and theoretical studies have been conducted to investigate CdSe nanostructures including nanowires, nanospheres, nanorods, nanocrystals, and 2D nanosheets . In 2009, Son et al successfully synthesized free‐standing semiconductor CdSe nanosheets with a thickness of 1.4 nm.…”

The electronic and optical properties of CdSe nanosheet under uniform strain are investigated using first‐principles calculations. The band structure, density of states and optical spectra of CdSe nanosheet are calculated. The conduction bands are found to move towards the Fermi energy when strain changes from compressive to tensile. This leads to a decrease in the energy bandgap. Optical properties also show strong dependence on strain. The peaks of the dielectric function are mapped with corresponding electron transitions between the bands. All peaks experiences redshifts under increasing strain. This phenomenon is explained via the analysis on the band structures. Other optical properties including the index of refraction, the extinction coefficient, the reflectivity, the absorption coefficient, and the energy‐loss function were also calculated to investigate the mechanism of optical transitions of CdSe nanosheet.
