    Optical Absorption, Raman, and Photoluminescence Excitation Spectroscopy of Inhomogeneous InGaN Films

    InxGal-xN films with x=0.06 to x=0.49 were characterized by optical transmittance, Raman, and photoluminescence excitation spectroscopies. Previous microstructural characterizations detected phase separation only...

    Determination of interfacial heat transfer coefficients in casting and quenching using a solution technique for inverse problems based on the boundary element method

    Both casting and quenching are processes during which several physical phenomena like heat transfer, fluid flow, phase transformation,etc. interact in a complex manner. To obtain a nu-merical model which is capab...

    On plastic zones and fracture strengths in some metal matrix composites

    Based on a Dugdale-type approach for cancelling the singularity at the crack tip, an attempt was made to predict the overall stress distributions, as well as the size of the plastic zone found in notched metal...

    In Situ Characterization of the Pulsed Laser Deposition of Magnetic Thin Films

    Pulsed Laser Deposition (PLD) has been proven as an effective means of depositing films from refractory targets. In our earlier work, either Nd/YAG or excimer lasers, interacting directly with target surfaces,...
