First Principles Study of Metal/Bi2Te3Interfaces: Implications to Improve Contact Resistance
Keyword(s):
AbstractWe investigate the band offsets and stability for Ni/Bi2Te3and Co/Bi2Te3interfaces by first principles calculations. It is found that the surface termination strongly affects the band offsets. Ni and Co are found to form Ohmic contacts to Bi2Te3. The interface formation energies for Co/Bi2Te3interfaces are much lower than those of Ni/Bi2Te3interfaces. Our calculations are consistent with the experimental data.
