The study describes diffusion of elemental sodium into p -type samples of Bridgman-grown CuInSe 2+x , causing a change from p - to n -type behavior at the surface and deep into the material. This resulted in the creation of Na 1s and Se 3d XPS peaks

Using multi-crystalline samples of Bridgman-grown CuInSe2+x, containing added quantities of elemental sodium or Na2Se, detailed XPS measurements were made to determine the location and action of the sodium. Here, the XPS peaks Se 3d, Na 1s and O 1s w

Ingots containing monocrystals of CuInSe 2 , grown in this laboratory from stoichiometric melts by a one-ampoule Bridgman method, have always been found to be p-type but become n-type if 0.3 at.% or more of elemental sodium is added to the pre-growth

Elemental sodium Na0 was introduced into Bridgman melts with the two compositions CuInSe2 (stoichiometric) and CuInSe2.2 (excess Se) in amounts of 0, 0.1, 0.5, 1, 2 and 3 at.%. In the resulting Bridgman-grown ingots brittleness generally increased wi
