Experimental and theoretical study of ultraviolet-induced structural/optical instability in nano silicon-based luminescence
Malloy, James; Mantey, Kevin; Maximenko, Yulia; Bahçeci, Ersin; Morgan, Huw; Yamani, Zain; Boparai, Jack; Puthalath, Krithik; Nayfeh, Munir Hasan (American Institute of Physics Inc., 2018)Nano silicon is emerging as an active element for UV applications due to quantum confinement-induced widening of the Si bandgap, amenability to integration on Si, and less sensitivity to temperature. NanoSi-based UV ... -
Wideband luminescence from bandgap-matched Mg-based Si core-shell geometry nanocomposite
Kocyiğit, Adem; Elhalawany, Noha; Bahçeci, Ersin; Enders, Brian; Puthalath, Krithik; Abuhassan, Laila; Yamani, Zain; Nayfeh, Munir (American Institute of Physics Inc., 2018)We use wet treatment to integrate red-luminescent Si nanoparticles with Mg-based wide-bandgap insulators Mg(OH) and MgO (5.7 and 7.3 eV respectively). In the process, Mg2+ is reduced on Si nanoparticle clusters, while ...
