Title Grain boundary specific resistance and RRR measurements in large grain pure niobium
Type Poster materials / surface effects
Abstract Preliminary results have showed some variation of grain boundary specific resistance and RRR measurements with surface treatment. A continuous degradation of the RRR appears upon further chemical or electrochemical treatment. This paper shows further investigation to try to determine where those variations originate from. The question to know if it arises from surface effect or enhanced diffusion at grain boundary is discussed.
