Transformation of germanium to fluogermanates
S. Kalem, O. Arthursson, I. Romandic
The surface of a single crystal Germanium wafer was transformed to crystals of germanium fluorides and oxides upon exposure to a vapor of HF and HNO3 chemical mixture. Structure an…
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…
Photoluminescence from Silicon nanoparticles embedded in ammonium silicon hexafluoride
Seref Kalem, Peter Werner, Vadim Talalaev +3
Silicon (Si) nanoparticles (NPs) were synthesized by transforming Si wafer surface to ammonium silicon hexafluoride (ASH) or (NH4)2SiF6 under acid vapor treatment. Si-NPs are embed…
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…
Searching for Overionized Plasma in the Gamma-ray Emitting Supernova Remnant G349.70.2
Tülün Ergin, Aytap Sezer, Lab Saha +3
G349.70.2 is a supernova remnant (SNR) expanding in a dense medium of molecular clouds and interacting with clumps of molecular material emitting gamma rays. We analyzed the gam…
An algebraic characterization of a Dehn twist for nonorientable surfaces
Ferihe Atalan
Let be a nonorientable surface of genus \ \ with \ -punctures. In this note, we will give an algebraic characterization of a Dehn twist about a simple closed c…
