, J. R. (2014). Photo-initiated chemical vapor deposition of thin films using syngas for the functionalization of surfaces at room temperature and near-atmospheric pressure. Surface and Coatings Technology, 244, p. 98-108. doi:10.1016/j.surfcoat.2014 This study addresses the current limiting factor, namely the cost issue, by using simple gas precursors, using an a↵ordable initiation source and operating under normal condition. This approach di↵ers from the current approaches which use expensive solvents as precursors, energy consuming-sources of initiation (e.g.high temperature, plasma and VUV) and operate under high vacuum and/or high temperatures. While the current paradigm is to target the peak absorption of a molecule, the present study indicates that long chain polymerized products can be formed from o↵-peak wavelength. It has been found that photo-initiated deposition occurs and that a wide range of water contact angles, from 5 to 118 , can be obtained by manipulating the experimental conditions. A multilinear empirical model has been derived, and it predicts fairly well the contact angles obtained as a function of the di↵erent experimental parameters.

We have investigated the effect of post-growth rapid thermal annealing on the low-temperature photoluminescence (PL) spectra of self-assembled InAs quantum dots (QDs) grown in InP(001) by chemical-beam epitaxy using both conventional and modified capping procedures. As-grown samples are characterized by a broad emission peak centered near 800–900 meV corresponding to distinct QD families of different sizes with no observable wetting-layer emission. Rapid thermal anneals were performed at 650 to 800 °C for 210 s, resulting in blueshifts of up to 120 meV due to intermixing. While the PL emission energies of the various QD families shift at similar rates upon annealing, the peak widths remain approximately constant. Finally, we show that the growth of a low-temperature InP cap layer containing a large number of point defects significantly enhances interdiffusion and results in PL blueshifts in excess of 300 meV.
