“…The lower energy peak mainly originates from near-band-edge (NBE) emission of GaAs substrate due to the thin thickness (130-285 nm) of CdSe epilayers in this work, which is also supported by PL measurement of a bared n-GaAs substrate (not shown here). The higher energy peak at 1.665 eV is in good agreement with the bandgap of cubic CdSe (1.67 eV) at RT [5,10]. Therefore, it is ascribed to the NBE emission of zinc blende CdSe.…”

“…Samarth et al [5] firstly reported the growth of cubic CdSe epilayers on GaAs(0 0 1) by molecular beam epitaxy (MBE). After that, several groups presented the structural and optical properties of zinc blende CdSe layers prepared by various techniques, including MBE [6][7][8], metalorganic chemical vapor deposition (MOCVD) [9,10], electron beam evaporation [11], closed space sublimation [12], and chemical bath deposition (CBD) [13]. Among these growth methods, MBE is thought to be one of the best processes of obtaining high-quality epitaxial films due to its ultrahigh vacuum (UHV) ambient and relatively slow growth rate.…”

“…All precursors may be in the gas phase, or one precursor may be present on the substrate to assist in nucleation. The development of this method is centered around semiconductor thin films. − Once more, metal oxides − and sensitizing semiconductors − can be prepared following CVD processing, and recent work involves structural and morphological varieties of semiconductors that may boost future photoelectrochemical solar cell performance.…”

He earned his doctoral degree (1979) in Physical Chemistry from the Bombay University and carried out postdoctoral research at Boston University (1979University ( -1981 and University of Texas at Austin (1981Austin ( -1983. He joined Notre Dame in 1983 and initiated a successful research project on utilizing semiconductor nanostructures for light energy conversion. His major research interests are in three areas: (1) to understand interfacial processes and catalytic reactions at nanostructured semiconductor interface, (2) to develop semiconductor hybrid assemblies for solar cells and solar fuels, and (3) carbon nanostructure architectures for energy conversion and storage. He has authored more than 350 peer-reviewed journal papers, review articles, and book chapters with more than 20000 citations. He has also edited three books in the area of nanoscale materials.Kevin Tvrdy (far left) received his Bachelor's degree in Chemistry from the University of Nebraska in 2005, after which he worked for one year at Streck Laboratories as an R&D technician. He is currently pursuing his doctoral degree at the University of Notre Dame in the Department of Chemistry and Biochemistry under the direction of Prashant V. Kamat. His current research centers on the application of ultrafast spectroscopic measurements to better understand and improve upon electron transfer phenomena in photovoltaic devices. In his free time, Kevin enjoys spending time with his wife Jessica outdoors. David R. Baker (far right) is a Ph.D. candidate in the Department of Chemical and Biomolecular Engineering at the University of Notre Dame, and Radiation Laboratory. He earned his Bachelor's degree in Chemical Engineering at the University of Washington in 2006, where he researched interfacial water phenomena and methylotrophic bacterial populations. His current research focuses on electrode-electrolyte interactions and developing nanoarchitectures within quantum dot solar cells. He has interned with the Jet Propulsion Laboratory and the United States Department of State. Emmy J.

“…[3][4][5][6][7][8][9][10]. As it is well known that CdSe can be crystallized in zinc blende (cubic), wurtzite (hexagonal) or wurtzite-zinc blende mixed phases, the transformation in crystalline phases of CdSe has attracted much attention in the past [11]. Some researchers observed the phase transformation by annealing [12] or mechanically grinding CdSe samples [13].…”
