Electronic properties of the SnSe–metal contacts: First-principles study |
Partial density of state for the SnSe/metal contacts (a)–(d) for Ag substrate, (e)–(h) for Au substrate, (i)–(n) for Ta substrate. The black lines and color lines stand for before adsorption and after adsorption, respectively. The Fermi level is set to zero and marked by a dotted line. |
