Polarization-based surface enhanced Raman scattering from single colloidal DNA decorated with 3 nm silicon nanoparticles
Mantey, Kevin; Quagliano, Lucia; Rezk, Ayman; Palleschi, Simonetta; Abuhassan, Laila; Nayfeh, Ammar; Bahçeci, Ersin; Nayfeh, Munir H. (American Institute of Physics Inc., 2021)Surface enhanced Raman scattering (SERS), in which sample molecules are placed in the proximity of conducting nanostructures, subjects the molecules to intense electron oscillation (plasmon) field. The intense field, ... -
Proximal probe-like nano structuring in metal-assisted etching of silicon
Bahçeci, Ersin; Enders, Brian; Yamani, Zain Hassan; Tokmoldin, Serekbol; Taukenov, Aman; Abuhassan, Laila; Nayfeh, Munir (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) ... -
Time-thermo-dynamics of anti-Stokes and Stokes scattering and luminescence in 1-nm silicon nanoparticles: Toward an optical nanorefrigerator
Nayfeh, Munir H.; Morgan, Huw; Nayfeh, Ammar; Bahçeci, Ersin; Abuhassan, Laila (American Institute of Physics Inc., 2022)The thermodynamics of nanosystems is interesting, as they constitute the transition between the atomistic and solid states. This is empowered by the development of tools to manipulate individual atoms and perform atomistic ... -
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 ...
