Electronic structure of ABC-stacked multilayer graphene and trigonal warping: A first principles calculation
Yelgel, Celal (Iop Publishing Ltd, 2016)We present an extensive density functional theory (DFT) based investigation of the electronic structures of ABC-stacked N-layer graphene. It is found that for such systems the dispersion relations of the highest valence ... -
First-principles modeling of GaN/MoSe2 van der Waals heterobilayer
Yelgel, Celal (Scientific Technical Research Council Turkey-Tubitak, 2017)We investigate structural and electronic properties of the graphene-like gallium nitride (GaN) monolayer deposited on a MoSe2 monolayer by using density functional theory with the inclusion of the nonlocal van der Waals ... -
An improved sensorless DTC-SVM for three-level inverter-fed permanent magnet synchronous motor drive
Güven, Selçuk; Usta, Mehmet Ali; Okumuş, Halil İbrahim (Springer, 2018)A speed-sensorless control strategy is investigated in a wide speed range based on extended Kalman filter (EKF) and direct torque control with space vector modulation (DTC-SVM) for three-level cascaded H-bridge inverter-fed ... -
Stacking domains and dislocation networks in marginally twisted bilayers of transition metal dichalcogenides
Enaldiev, Vladimir V; Zolyomi, Viktor; Yelgel, Celal; Magorrian, Samuel J.; Fal'ko, Vladimir I. (Amer Physical Soc, 2020)We apply a multiscale modeling approach to study lattice reconstruction in marginally twisted bilayers of transition metal dichalcogenides (TMD). For this, we develop density functional theory parametrized interpolation ... -

Surface termination dependence of electronic and optical properties in Ti2CO2 MXene monolayers
Kandemir, Zafer; Torun, Engin; Paleari, Fulvio; Yelgel, Celal; Şevik, Cem (Amer Physical Society, 2022)Two-dimensional (2D) MXenes are a rapid growing family of 2D materials with rich physical and chemical properties where their surface termination plays an essential role. Among the various 2D MXenes, function-alization of ... -
Tunable electronic properties of van der Waals heterostructures composed of stanene adsorbed on two-dimensional, graphene-like nitrides
Yelgel, Celal (Amer Inst Physics, 2019)We investigated the structural stability and electronic properties of stanene/graphene-like nitride (stanene/XN, X = Al, B, and Ga) heterostructures using first-principles calculations. the results reveal that stanene ...
