Polarization for arbitrary discrete memoryless channels
Eren Sasoglu, Emre Telatar, Erdal Arikan
Channel polarization, originally proposed for binary-input channels, is generalized to arbitrary discrete memoryless channels. Specifically, it is shown that when the input alphabe…
Two-dimensional boson-fermion mixtures
A. L. Subasi, S. Sevincli, P. Vignolo +1
Using mean-field theory, we study the equilibrium properties of boson-fermion mixtures confined in a harmonic pancake-shaped trap at zero temperature. When the modulus of the s-wav…
Modification of anatase TiO(001) surface electronic structure by Au impurity
E. Mete, O. Gulseren, S. Ellialtioglu
We have used density functional theory calculations based on the projector augmented wave method to investigate the electronic structure of Au-incorporated anatase TiO(001) sur…
Analysis of Strain Fields in Silicon Nanocrystals
Dündar E. Yılmaz, Ceyhun Bulutay, Tahir Çağın
Strain has a crucial effect on the optical and electronic properties of nanostructures. We calculate the atomistic strain distribution in silicon nanocrystals up to a diameter of 3…
Pt-incorporated anatase TiO2(001) surface for solar cell applications : First-principles density functional theory calculations
E. Mete, D. Uner, O. Gulseren +1
First-principles density functional theory calculations were carried out to determine the low energy geometries of anatase TiO(001) with Pt implants in the sublayers as substit…
