Thermally Stable, Low‐Resistance Cu Alloy Contacts for Mg3(Sb, Bi)2 Thermoelectric Materials by Two‐Step Contacting

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Selection of suitable electrical contact is crucial for achieving low specific contact resistivity (ρc) at the electrode/thermoelectric (TE) material interface. Sustaining low ρc is far more critical than merely attaining a low value. Moreover, the conversion efficiency (η) and durability are often limited by unstable contact interfaces at various ...
