Fig. S1 XRD patterns of ZnO NR, NC and NT arrays deposited on ITO substrates corresponding to Figs. 1i, 1iv and 2a, respectively, indexed according to the hexagonal wurtzite structure (JCPDS No. 36-1451). The peaks associated with In 2 O 3 from ITO substrates are labeled for clarity.

GaN layers with wurtzite structure were found to exhibit intense photoluminescence (PL) at 3.47eV (T = 10K) corresponding to recombination of excitons bound to neutral donors. The dependence of this luminescence on the growth conditions, layer thickness and density of excitation power was studied. New PL bands were evidenced in the UV region under high levels of excitation (Iexc 3 0.56mJ/cm ).

A facile precursor dependent single step, one pot solution based synthesis of wurtzite and chalcopyrite polymorphs of CuFeS2 has been developed by reacting a Cu(I) thiourea complex with Fe2(SO4)3 and FeCl3 separately in ethylene glycol. The phases have been characterized by structural refinements, SEM-EDX, TEM-SAED, Raman, UV-Visible spectroscopy and TGA measurements.

Self-catalyzed growth of GaAs nanowires are widely ascribed to the vapor-liquid-solid (VLS) mechanism due to the presence of Ga particles at the nanowire tips. Here we report synthesis of self-catalyzed GaAs nanowires by molecular-beam epitaxy covering a large growth parameter space. By carefully controlling the Ga flux and its ratio with the As flux, GaAs nanowires without Ga particles and exh...

In this study, one-dimensional ZnO nanorod structures with different ratios of nickel doping were produced using the hydrothermal method. The presence in caused variations fundamental characteristics nanorods that grew on RF sputtered seed layer, such as crystallinity quality, morphology, diameter nanorods, band gap energy, resistance sample, and CO2 gas sensing. Produced samples found to form ...

ZnMgO thin films were grown by Molecular Beam Epitaxy on closely-lattice-matched MgO substrates with a Radio-Frequency (RF) generated oxygen plasma. The impact on the cubic ZnMgO of oxygen flow rate and applied RF power was investigated under a high vacuum condition (1E-6 Torr). Optical Emission Spectroscopy identified active species in the plasma including O, O + , and O þ 2. The emission inte...

Herein, we demonstrate that the stable AlScN model with wurtzite structure is described by small/negligible vacancy concentrations and minimal localized distortions.
