A DFT study of the adsorption of F atoms on germanene nanoribbons

A DFT study of the adsorption of F atoms on germanene nanoribbons

By Vo Van On, Nguyen Duy Khanh, Nguyen Thanh Tung, Hoang Van Ngoc and Huynh Thi Phuong Thuy
In the paper, we investigate the structure and electronic properties of the pristine germanene nanoribbon and four adsorption configurations of 1F and 2F on the substrate of germanene nanoribbon. We obtained the parameters of the most stable structures of pristine germanene nanoribbon and four adsorption configurations. The band structure and ...

On existence results for a nonlinear differential equation involving Caputo-Katugampola fractional derivative with a nonlocal initial condition

On existence results for a nonlinear differential equation involving Caputo-Katugampola fractional derivative with a nonlocal initial condition

By Bui Thi Ngoc Han, Nguyen Thi Linh
This paper is devoted to study a fractional equation involving Caputo-Katugampola derivative with nonlocal initial condition. Unlike previous papers, in this paper, the source function of problem is assumed having a singularity. We propose some reasonable conditions such that the problem has at least one mild solution or has a ...

Applying first principles to study the structural, electronic, and magnetic properties of Pr adsorbed ASiNRs

Applying first principles to study the structural, electronic, and magnetic properties of Pr adsorbed ASiNRs

By Thanh Tung Nguyen, Hoang Van Ngoc, Huynh Thi Phuong Thuy, Duy Khanh Nguyen, Vo Van On
Applying first-principles calculations, the investigation of the geometrical and electronic properties of Pr adsorption armchair silicene nanoribbons structure has been established. The results show that the bandgap doped Pr has been changed, which is the case for chemical adsorption on the surface of ASiNRs; this material became metallic with the ...
