Solid argon as a possible substrate for quasi-freestanding silicene
We study the structural and electronic properties of silicene on solid Ar(111) substrate using ab initio calculations. We demonstrate that due to weak interaction, quasi-freestanding silicene is realized in this system. The small binding energy of only $-32$ meV per Si atom also indicates the possib...
