This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Planar 110 GaAs nanowires and quantum dots grown by atmospheric MOCVD have been introduced to non-standard growth conditions such as incorporating Zn and growing them on free-standing suspended films and on 10° off-cut substrates. Zn doped nanowires exhibited periodic notching along the axis of the wire that is dependent on Zn/Ga gas phase molar ratios. Planar nanowires grown on suspended thin films give insight into the mobility of the seed particle and change in growth direction. Nanowires that were grown on the off-cut sample exhibit anti-parallel growth direction changes. Quantum dots are grown on suspended thin films and show preferential growth at certain temperatures. Envisioned nanowire applications include twin-plane superlattices, axial pn-junctions, nanowire lasers, and the modulation of nanowire growth direction against an impeding barrier and varying substrate conditions.

This book was released on 1991 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: III-V compound semiconductor materials have had much attention because of their application to high speed electronic and optoelectronic devices. For achieving these purposes, it is required to produce high quality samples with uniform layer thickness, no defects, and abrupt interfaces. For this metalorganic chemical vapor deposition (MOCVD) is one of the most important growth methods. In this study, transmission electron microscopy (TEM) was used for the characterization of epilayer structures grown by the MOCVD technique. High resolution electron microscopy (HREM), the two beam technique and the convergent beam technique (CBED) were used. Cross sectional, plan view and cleavage samples using the ion milling or chemical etching method were used for TEM sample preparation. Tetragonal distortion occurs in the strained layer superlattice (SLS). Misfit dislocations are found above a certain layer thickness (critical thickness) and the critical thickness is related to the total strain state in SLS. Composition measurements of In$sb{rm 1-x}$Ga$sb{rm x}$As in SLS using TEM has restrictions because of the misfit strain and the similarity of atomic scattering factors of Ga and In. But a low In concentration layer can be determined from the (002) dark field intensity ratio. The interface quality of heterostructures can be distinguished by 5 beam, 9 beam or more conditions at a (100) zone axis. Digital vector pattern recognition was found to be a powerful tool for quantization of interface quality.

This book was released on 1988 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic Layer Epitaxy (ALE) is a promising variation of conventional vapor phase epitaxy which achieves uniform growth of ultra-thin epitaxial layers by a self-limiting monolayer by monolayer deposition process. By developing a new regime of metalorganic chemical vapor deposition (MOCVD) growth, in which saturated surface reactions control the growth, it is possible to alternately deposit monolayers of column III and column V elements so that only one monolayer of the III-V compound semiconductor is deposited in every cycle of the deposition. In this thesis, ALE growth of single crystal GaAs, as well as AlAs and GaAs/AlGaAs heterostructures and devices is demonstrated. We have been able to grow extremely uniform ultra-thin epitaxial layers and quantum wells (QWs) with thickness variations of less than one monolayer per cm over an entire sample in an optimized reactor using ALE. The observed dependence of the growth rate on temperature and trimethylgallium flux is modeled by first order adsorption kinetics utilizing measured reaction rate constants. The low temperature photoluminescence (PL) of ALE grown GaAs QW's exhibit narrow line intrinsic luminescence with linewidths comparable to the best reported values by conventional MOCVD. (jhd).
