Charging/discharging mechanism in Mg3Bi2 anode for Mg-ion batteries; The role of the spin-orbit coupling
M. Hussein N. Assadi, Christopher J. Kirkham, Ikutaro Hamada +1
Using density functional calculations, we examine insertion/extraction of Mg ions in Mg3Bi2, an interesting Mg-ion battery anode. We found that a (1 1 0) facet is the most stable t…
Towards surface diffusion potential mapping on atomic length scale
Renan Villarreal, Christopher J. Kirkham, Alessandro Scarfato +2
The surface diffusion potential landscape plays an essential role in a number of physical and chemical processes such as self-assembly and catalysis. Diffusion energy barriers can…
Atomic layer doping of Mn magnetic impurities from surface chains at a Ge/Si hetero-interface
Koichi Murata, Christopher Kirkham, Satoshi Tsubomatsu +7
We realize Mn -doping into Si and Si/Ge interfaces using Mn atomic chains on Si(001). Highly sensitive X-ray absorption fine structure techniques reveal that encapsulation at ro…
Electronic coupling between Bi nanolines and the Si(001) substrate: An experimental and theoretical study
M. Longobardi, C. J. Kirkham, R. Villarreal +3
Atomic nanolines are one dimensional systems realized by assembling many atoms on a substrate into long arrays. The electronic properties of the nanolines depend on those of the su…
Sub-atomic electronic feature from dynamic motion of Si dimer defects in bismuth nanolines on Si(001)
C. J. Kirkham, M. Longobardi, S. A. Koster +2
Scanning tunneling microscopy (STM) reveals unusual sharp features in otherwise defect free bismuth nanolines self-assembled on Si(001). They appear as subatomic thin lines perpend…
Intrinsic origin of electron scattering at 4H-SiC(0001)/SiO
Shigeru Iwase, Christopher James Kirkham, Tomoya Ono
We introduce a first-principles study to clarify the carrier-scattering property at the SiC/SiO. Interestingly, the electron transport at the conduction-band edge is significan…
