Near-IR photoluminescence from Si/Ge nanowire grown silicon wafers: effect of HF treatment
Seref Kalem, Peter Werner, Vadim Talalaev
We present the room temperature (RT) near-infrared (NIR) photoluminescence (PL) properties of Si/Ge nanowire (NW) grown silicon wafers which were treated by vapor of HF:HNO3 chemic…
Ellipsometry studies of Si/Ge superlattices with embedded Ge dots
Seref Kalem, Orjan Arthursson, Peter Werner
In this paper, we present an analysis for treating the spectroscopic ellipsometry response of Si/Ge superlattices (SL) with embedded Ge dots. Spectroscopic ellipsometry (SE) measur…
Controlling photon emission from silicon for photonic applications
Seref Kalem
The importance of a photon source that would be compatible with silicon circuitry is crucial for data communication networks. A photon source with energies ranging from UV to near…
Black Silicon with high density and high aspect ratio nanowhiskers
S Kalem, P Werner, Ö Arthursson +5
Physical properties of black Silicon (b-Si) formed on Si wafers by reactive ion etching in chlorine plasma are reported in an attempt to clarify the formation mechanism and the ori…
