Lattice mismatched epitaxy of heterostructures for non-nitride green light emitting devices
(Massachusetts Institute of Technology, 2008)In this project, we implement modern metal organic chemical vapor deposition (MOCVD) technology to fabricate monolithic platforms which integrate traditionally incompatible materials with the ultimate goal of achieving ... -
Lattice-mismatched epitaxy of AlInP and characterization of its microstructure and luminescence
(Massachusetts Institute of Technology, 2014)The synthesis of high-quality III-V ternary alloy semiconductors is vital to the success of major technologies such as LEDs, laser diodes, high-efficiency solar cells and power electronics. However, the epitaxy of ternary ... -
LCD, low-temperature soldering and compound semiconductor : the sources, market, applications and future prospects of indium in Malaysia
(Massachusetts Institute of Technology, 2006)Indium is a minor but very valuable metal. Decreasing supplies of indium from refining and increasing demands from LCD, low-temperature soldering and compound semiconductors have stimulated the indium price increase ... -
Learning-Derived Cost Evolution in Materials Selection
(Massachusetts Institute of Technology, 2010)Materials selection is a complex, but important, problem for manufacturing firms. Poor material choices can negatively affect the firm's market share or profits. In the face of this complexity, most selection methods make ... -
Life extension of structural components via an improved nondestructive testing methodology
(Massachusetts Institute of Technology, 2010)An experimental study was performed to determine the flaw detection sensitivity of advanced nondestructive testing (NDT) techniques with respect to structural applications. The techniques analyzed exemplify the incorporation ... -
Life-cycle analysis of hazardous chemicals in the Department of Materials Science & Engineering
(Massachusetts Institute of Technology, 2013)MIT policies set forth by the Department of Environment, Health, and Safety (EHS) require that all laboratories maintain a chemical inventory to properly document the use of hazardous chemicals. While EHS has provided a ... -
Ligand shell morphology of water-soluble mixed-monolayer protected gold nanoparticles
(Massachusetts Institute of Technology, 2007)Nanoparticles comprise a versatile class of nanomaterials that consist of particles that have a characteristic length scale less than 100nm. They are on a similar length scale as many biological elements, so it is fitting ... -
Light emitting characteristics and dielectric properties of polyelectrolyte multilayer thin films
(Massachusetts Institute of Technology, 1999)This thesis focuses on the use of a new sequential adsorption technique to deposit thin polyelectrolyte multilayer films. This involves alternately dipping a substrate into dilute aqueous solutions of a positively charged ... -
Limited-area growth of Ge and SiGe on Si
(Massachusetts Institute of Technology, 2011)The goal of this thesis is to develop and understand processing conditions that improve the surface morphology and reduce the dislocation density in limited-area heteroepitaxy of Ge and SiGe on Si (100) substrates. Low ... -
Lipid-coated micro- and nanoparticles as a biomimetic vaccine delivery platform
(Massachusetts Institute of Technology, 2010)Biomaterials provide a unique opportunity to control the display, release, and in vivo trafficking of vaccine components. We have designed and characterized a system for vaccine delivery that uses a "lipid surfactants" ... -
