TL;DR: The room temperature optical properties of single crystal hexagonal GaN films on (0001) sapphire grown by metalorganic chemical vapor deposition are reported in this article, where the energy gap was determined as 3.39 and 3.400 eV by optical transmission and photoreflectance, respectively, and the refractive index of GaN film as the function of photon energy was obtained.

TL;DR: Calculation results suggest that the ZnO nanowire encapsulated in (9, 9)-CNT is the most stable structure from the view of formation energy.

TL;DR: The reproducible capability of implantation and laser annealing at selective area enable the realization of high efficient lateral junction solar cells, which can ensure extreme light trapping and efficient charge separation.

TL;DR: In this paper, the charge storage characteristics in the metal-oxide-semiconductor memory structure based on gradual Ge1−x6∕Si heteronanocrystals (HNCs) were investigated by using capacitance-voltage measurements.

TL;DR: The correlation between surface structural and luminescence properties of InGaN epi-layers grown by metal organic chemical vapour deposition has been investigated in this paper, where ring-shaped regions with high In-content are observed around V-pits by spatial resolved cathodoluminescence and energy dispersive X-ray spectroscopy.
