Coherent phonon motions and ordered vacancy compound mediated quantum path interference in Cu-poor CuInGaSe (CIGS) with attosecond transient absorption
Hugo Laurell, Jonah R. Adelman, Elizaveta Yakovleva +7
In this study, coherent phonon motion is observed in bandgap excited CuInGaSe (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectro…
Experimental and theoretical study of stable and metastable phases in sputtered CuInS
Jes K. Larsen, Kostiantyn V. Sopiha, Clas Persson +2
The chalcopyrite Cu(In,Ga)S has gained renewed interest in recent years due to the potential application in tandem solar cells. In this contribution, a combined theoretical a…
First-Principles Mapping of the Electronic Properties of Two-Dimensional Materials for Strain-Tunable Nanoelectronics
Kostiantyn V. Sopiha, Oleksandr I. Malyi, Clas Persson
Herein, we demonstrate that first-principles calculations can be used for mapping electronic properties of two-dimensional (2d) materials with respect to non-uniform strain. By inv…
Noble gas as a functional dopant in ZnO
Oleksandr I. Malyi, Kostiantyn V. Sopiha, Clas Persson
Owing to fully occupied orbitals, noble gases are considered to be chemically inert and to have limited effect on materials properties under standard conditions. However, using fir…
Energy, phonon, and dynamic stability criteria of 2d materials
Oleksandr I. Malyi, Kostiantyn V. Sopiha, Clas Persson
First-principles calculations have become a powerful tool to exclude the Edisonian approach in search of novel 2d materials. However, no universal first-principles criteria to exam…
Suppression of Surfaces States at Cubic Perovskite (001) Surfaces by CO Adsorption
Kostiantyn V. Sopiha, Oleksandr I. Malyi, Clas Persson +1
By using first-principles approach, the interaction of CO with (001) surfaces of six cubic ABO perovskites (A = Ba, Sr and B = Ti, Zr, Hf) is studied in detail. We show…
Tailoring electronic properties of multilayer phosphorene by siliconization
Oleksandr I. Malyi, Kostiantyn V. Sopiha, Ihor Radchenko +2
Controlling a thickness dependence of electronic properties for two-dimensional (2d) materials is among primary goals for their large-scale applications. Herein, employing a first-…
Band Gap Modulation of SrTiO3 upon CO2 Adsorption
Kostiantyn V. Sopiha, Oleksandr I. Malyi, Clas Persson +1
CO2 chemisorption on SrTiO3(001) surfaces is studied using ab initio calculations in order to establish new chemical sensing mechanisms. We find that CO2 adsorption opens the mater…
