Gate induced monolayer behavior in twisted bilayer black phosphorus
Cem Sevik, John R. Wallbank, Oguz Gulseren +2
Optical and electronic properties of black phosphorus strongly depend on the number of layers and type of stacking. Using first-principles calculations within the framework of dens…
APPD: Adaptive and Precise Pupil Boundary Detection using Entropy of Contour Gradients
Cihan Topal, Halil Ibrahim Cakir, Cuneyt Akinlar
Eye tracking spreads through a vast area of applications from ophthalmology, assistive technologies to gaming and virtual reality. Precisely detecting the pupil's contour and cente…
Self-acceleration in non-Hermitian Systems
C. Yuce, Z. Turker
We study self-acceleration in PT and non-PT symmetric systems. We find some novel wave effects that appear uniquely in non-Hermitian systems. We show that integrable self-accelerat…
Distinct Correlation between the Vibrational and Thermal Transport Properties of Group \textrm{VA} Monolayer Crystals
Tugbey Kocabas, Deniz Cakir, Oguz Gulseren +3
The investigation of thermal transport properties of novel two dimensional materials is crucially important in order to assess their potential to be used in future technological ap…
Piezoelectricity in two-dimensional materials: a comparative study between lattice dynamics and ab-initio calculations
K. H. Michel, D. Cakır, C. Sevik +1
Elastic constant C_{11} and piezoelectric stress constant e_{1,11} of two-dimensional (2D) dielectric materials comprising h-BN, 2H MoS2 and other transition metal dichalcogenides…
Greedy Search for Descriptive Spatial Face Features
Caner Gacav, Burak Benligiray, Cihan Topal
Facial expression recognition methods use a combination of geometric and appearance-based features. Spatial features are derived from displacements of facial landmarks, and carry g…
