Si-ZnO thin-film transistors were fabricated using atomic layer deposition (ALD) then annealed in oxygen at 400°C for 1 hour and are demonstrated. Hexagonal wurtzite structure ZnO was presented all films, with a primary diffracted peak the (100) direction regardless of annealing treatment. First-principle density functional theory (DFT) calculations supported observed crystalline characteristic...

There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...

A lithium-boron complex, lithium tetra (2-methyl 8-hydroxy quinolinato) boron (LiBqm4), which emits greenish-blue light has been synthesized by the reaction of LiBH4 with 2-methyl 8-hydroxyquinoline in a molecular weight ratio of 1:4, and used for organic light emitting diodes (OLEDs) fabrication. The complex has been characterized by optical absorption, Fourier Transform Infrared (FTIR), photo...

Habituation phenomena and decrements of neural responses in isolated nervous structures have been related to depression of synaptic potentials (Bruner & Kehoe, 1970; Kandel et al. 1970; Horn & Wright, 1970; Zucker, 1972). However, previous research (Stephens, 1973) has shown that repeated intracellular stimulation of neurones in the isolated abdominal ganglion of Aplysia caUfomica produces resp...

Amorphous carbon (a-C) has been shown to be intrinsically p-type, and polymeric a-C ~PAC! possesses a wide Tauc band gap of 2.6 eV. We have replaced the p-type amorphous silicon carbide layer of a standard amorphous silicon solar cell with an intrinsic ultrathin layer of PAC. The thickness of the p layer had to be reduced from 9 to 2.5 nm in order to ensure sufficient conduction through the PAC...
