Theoretical investigation of the role of the organic cation in methylammonium lead iodide perovskite
Veysel Çelik
The hybrid halide perovskite CHNHPbI is easy to manufacture and inexpensive. Despite these, its efficiency as a solar cell is comparable to today's efficient solar cell…
Electronic and optical properties of Cr and Cr-N doped anatase TiO2 from screened Coulomb hybrid calculations
Veysel Celik, Ersen Mete
We studied the electronic and atomic structures of anatase TiO2 codoped with Cr and N using hybrid density functional theory calculations. Nonlocal screened Hartree-Fock exchange e…
Range separated hybrid exchange-correlation functional analyses of W and/or N(S) (co)doped anatase TiO_2
Veysel Çelik, Ersen Mete
Electronic properties and atomic structures of W, N, S, W/N, and W/S dopings of anatase TiO_2 have been systematically investigated using the density functional theory (DFT). The e…
A theoretical analysis of small Pt particles on rutile TiO(110) surfaces
Veysel Celik, Hatice Unal, Ersen Mete +1
The adsorption profiles and electronic structures of Pt (n = 1--4) clusters on stoichiometric, reduced and reconstructed rutile TiO(110) surfaces were systematically studie…
