文摘
- •
Ni electrode was successfully bonded to n-type PbTe using a one-step spark plasma sintering technique.
- •
A single phase barrier layer of nickel telluride was formed between Ni and PbTe with a constant thickness of 30 μm.
- •
Perfect consistency of Ni/Ni1.43Te/PbTe counterparts was achieved along the entire interface with no defects.
- •
Aging of obtained assembly indicates no degradation of interphase due to continuous reaction.
