Proximal probe-like nano structuring in metal-assisted etching of silicon

Bahçeci, Ersin; Enders, Brian; Yamani, Zain Hassan; Tokmoldin, Serekbol Zh H.; Taukenov, Aman; Abuhassan, Laila H.; Nayfeh, Munir H. (American Institute of Physics Inc., 2019)

We use silicon having multiple crystalline orientation domains and high metal doping in metal assisted chemical etching (MACEtch) in HF/H2O2. In device-quality silicon, MACEtch produces high-aspect ratio anisotropic (1-D) ...
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 ...
