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 ... -
CVD GROWTH and CHARACTERIZATION OF 2D TRANSITION METAL DICHALCOGENIDES, MoS2 and WS2
Perkgöz, Nihan Kosku (2017)Two-dimensional transition metal dichalcogenides (TMDC), specifically molybdenum disulfide and tungsten disulfide have received significant attention as their direct bandgap exhibits a shift from indirect to direct as the ... -
Highly polarized light emission by isotropic quantum dots integrated with magnetically aligned segmented nanowires
Uran, Can; Erdem, Talha; Güzeltürk, Burak; Perkgöz, Nihan Kosku; Jun, Shinae; Jang, Eunjoo; Demir, Hilmi Volkan (Amer Inst Physics, 2014)In this work, we demonstrate a proof-of-concept system for generating highly polarized light from colloidal quantum dots (QDs) coupled with magnetically aligned segmented Au/Ni/Au nanowires (NWs). Optical characterizations ... -
Investigation of Single-Wall MoS2 Monolayer Flakes Grown by Chemical Vapor Deposition
Perkgöz, Nihan Kosku; Bay, Mehmet (Shanghai Jiao Tong University Press, 2016)Recently, two-dimensional monolayer molybdenum disulfide (MoS2), a transition metal dichalcogenide, has received considerable attention due to its direct bandgap, which does not exist in its bulk form, enabling applications ... -
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 ...
