Photonic light trapping in silicon nanowire arrays: deriving and overcoming the physical limitations
Sebastian W. Schmitt, Silke H. Christiansen
Hexagonally aligned, free-standing silicon nanowire (SiNW) arrays serve as photonic resonators which, as compared to a silicon (Si) thin film, do not only absorb more visible (VIS)…

Observation of strongly enhanced photoluminescence from inverted cone-shaped silicon nanostuctures
Sebastian W. Schmitt, George Sarau, Silke H. Christiansen
Silicon nanowires (SiNWs) attached to a wafer substrate are converted to inversely tapered silicon nanocones (SiNCs). After excitation with visible light, individual SiNCs show a 2…
