Current-voltage characteristics of ZnO nanostructures were studied under different gas ambient using nonequilibrium Green's function and density functional theory, DFT technique. It was found that I-V characteristics of ZnO nanostructures depend strongly on the type of gas molecules present. The sensitivity factor of more than 200% achieved with the presence of a single molecule of NO 2 gas. Meanwhile, there were no significant changes towards CO and NH 3 gas molecules. However, CO adsorption can significantly suppress the transmission spectrum of ZnO nanostructures. Under the same applied bias voltage, the current through ZnO nanostructures decreases with increasing CO concentrations.

Density functional theory is utilized for scrutinizing the interaction of Glycine amino acid (Gly) with the Si12C12, BSi11C12, NSi11C12, BSi12C11, and NSi12C11 nanocages. The adsorption and deformation energy, solvent effect, topological parameters of atom in the molecule (AIM), time-dependent (TD-DFT), reduced density gradient (RDG), natural bonding (NBO), and quantum descriptors for all considered complexes of Gly&SiC nanocages are computed. The adsorption and enthalpy energy of formation all considered Gly&SiC nanocage complexes are exothermic, and interaction of Gly from oxygen site (C = O) with NSi11C12 and BSi12C11 nanocage is more favorable than other complexes. In the presence of water solvent, the formation of Gly&SiC nanocage complexes is non-spontaneous. The NBO charge and electrostatic potential (ESP) results display that the Gly molecule has a donor electron effect on the SiC nanocage surface. The gap energy and hardness property of Gly&SiC nanocage complexes depict that the conductivity and reactivity complex increases. The AIM and RDG parameters confirm that the bonding between Gly and SiC nanocage is partially covalent or electrostatic type. The electrical and optical properties of Gly with BSi11C12, NSi11C12, BSi12C11, and NSi12C11 nanocages change more than Si12C12 nanocages, and these nanocages can be applied as a selective sensor and absorber for Gly.

A field-emission light source with high luminance, excellent luminance uniformity, and tunable luminance characteristics with a novel lateral-gate structure is demonstrated. The lateral-gate triode structure comprises SiC nanowire emitters on a Ag cathode electrode and a pair of Ag gate electrodes placed laterally on both sides of the cathode. The simple and cost-effective screen printing technique is employed to pattern the lateral-gates and cathode structure on soda lime glass. The area coverage of the screen-printed cathode and gates on the glass substrate (area: 6 × 8 cm2) is in the range of 2.04% – 4.74% depending on the set of cathode-gate electrodes on the substrate. The lateral-gate structure with its small area coverage exhibits a two-dimensional luminance pattern with high brightness and good luminance uniformity. A maximum luminance of 10952 cd/cm2 and a luminance uniformity of >90% can be achieved with a gate voltage of 500 V and an anode voltage of 4000 V, with an anode current of 1.44 mA and current leakage to the gate from the cathode of about 10%.
