Bulk Electronic Structure of Ni2MnGa studied by Density Functional Theory and Hard X-ray Photoelectron Spectroscopy
Joydipto Bhattacharya, Pampa Sadhukhan, Shuvam Sarkar +4
A combined study employing density functional theory (DFT) using the experimentally determined modulated structures and bulk-sensitive hard x-ray photoelectron spectroscopy on sing…
Decagonal Sn clathrate on -Al-Ni-Co
Vipin Kumar Singh, Eva Pospisilova, Marek Mihalkovič +8
Decagonal quasiperiodic ordering of Sn thin film on -Al-Ni-Co, is shown based on scanning tunneling microscopy (STM), low-energy electron diffraction and density functional theo…
Electronic structure of Au-Sn compounds grown on Au(111)
Pampa Sadhukhan, Sajal Barman, Tufan Roy +4
The electronic structure of Au-Sn intermetallic layers of different compositions grown on Au(111) to the thickness of several nanometers has been studied in this work. The layer, i…
Unique Dirac and Triple point fermiology in simple transition metals and their binary alloys
Chiranjit Mondal, Chanchal K. Barman, Shuvam Sarkar +3
Noble metal surfaces (Au, Ag and Cu etc.) have been extensively studied for the Shockley type surface states (SSs). Very recently, some of these Shockley SSs have been understood f…
Dirac cone in a non-honeycomb surface alloy
Pampa Sadhukhan, Dhanshree Pandey, Vipin Kumar Singh +5
We demonstrate unexpected occurrence of linear bands resembling Dirac cone at the zone-center of AuSn surface alloy with $\left( \begin{smallmatrix} 2&1\\ 1&3 \end{smallmatrix}…
Enhancement of the density of states at the Fermi level due to oxygen atoms in noble metals
Sudipta Roy Barman, Aparna Chakrabarti
The interaction of oxygen with noble metals such as silver has been an important topic of research for many decades. Here, we show occurrence of a peak in the density of states (DO…
