most of the references mention about p-type conductivity of CZTS due to CuZn antisite defects. Is is possible to make stable n-type absorber layer of CZTS by controlling the atomic % and temperature?
You can get the similar or apropriate answer by searching the keyword in the GOOGLE SCHOLAR page. Usually you will get the first paper similar to your keyword.
