Journal ArticleDOI
Photoluminescence and cathodoluminescence studies of stoichiometric and oxygen-deficient ZnO films
TL;DR: In this article, the authors examined the spectra of stoichiometric and oxygen-deficient ZnO films grown on sapphire and found that the green and yellow emissions depend on the width of the free-carrier depletion region at the particle surface; the thinner the width, the larger the intensity.
Journal ArticleDOI
Experimental evidence for the quantum confinement effect in 3C-SiC nanocrystallites.
TL;DR: Using electrochemical etching of a polycrystalline 3C-SiC target and subsequent ultrasonic treatment in water solution, suspensions of 3C -SiC nanocrystallites that luminesce are fabricated.
Journal ArticleDOI
From Si nanotubes to nanowires : Synthesis, characterization, and self-assembly
TL;DR: In this article, a self-assembled localized microscopic electrochemical cell model was used to analyze the growth of triangular shaped SiNWs in a conventional vessel containing aqueous HF and AgNO3 solution.
Journal ArticleDOI
Current transport studies of ZnO/p-Si heterostructures grown by plasma immersion ion implantation and deposition
TL;DR: In this article, undoped and nitrogen-doped ZnO films were fabricated by plasma immersion ion implantation and deposition, and the transport properties of the undoped-ZnO∕p-Si and the N-drone-dope ZnNO√p-si diodes were explained in terms of the Anderson model and the space charge limited current model, respectively.
Journal ArticleDOI
Luminescence from colloidal 3C-SiC nanocrystals in different solvents
TL;DR: In this paper, the role of solvents in the luminescence from colloidal 3C-SiC suspensions was investigated, and a simple model was formulated to explain the photoluminescence spectra.
