What would be the best metal contact for Copper Indium Selenide (CIS) to measure the Hall effect? Film thickness is about 2 micron and it is copper poor (Cu/In = 0.9).
Yes, Neumann, H., & Tomlinson, R. D. (1990). Relation between electrical properties and composition in CuInSe2 single crystals. Solar cells, 28(4), 301-313 is useful. Thank you@ Michael Uebel.
