A comparative device performance assesment of CVD grown MoS2 and WS2 monolayers
Sar, Hüseyin; Özden, Ayberk; Yorulmaz, Büşra; Sevik, Cem; Perkgöz, Nihan Kosku; Ay, Feridun (Springer, 2018)In this study, optical and electronic transport properties of chemical vapor deposition (CVD) grown 2D WS2 and MoS2 based transistors and photodetectors are investigated and compared in ambient air by using 2D flakes grown ... -
Control of Optical Amplification Process with Extremely Low Background Loss in Er:Al2O3 Waveguides
Demirtaş, Mustafa; Odaci, Cem; Perkgöz, Nihan Kosku; Sevik, Cem; Ay, Feridun (IEEE, 2017)We report on record low-loss single mode a-Al2O3 planar waveguides and growth optimization of a-Er2O3 layers to control erbium-doping level of a-Al2O3 layers realized using Atomic Layer Deposition (ALD). Effect of growth ... -
Low Loss Atomic Layer Deposited Al2O3 Waveguides for Applications in On-Chip Optical Amplifiers
Demirtaş, Mustafa; Odaci, Cem; Perkgöz, Nihan Kosku; Sevik, Cem; Ay, Feridun (IEEE-Inst Electrical Electronics Engineers Inc, 2018)We present the growth and optimization of ultralow loss Si-based Al2O3 planar waveguides, which have a high potential to boost the performance of rare-earth ion doped waveguide devices operating at visible and C-band ... -
Vibrational and thermodynamic properties of alpha-, ss-, gamma-, and 6, 6, 12-graphyne structures
Perkgöz, Nihan Kosku; Sevik, Cem (IOP Publishing LTD, 2014)Electronic, vibrational, and thermodynamic properties of different graphyne structures, namely alpha-, ss-, gamma-, and 6, 6, 12-graphyne, are investigated through first principles- based quasi-harmonic approximation by ...
