Title: Ex-situ doped semiconductor transport layer

Abstract

A method of making an ex-situ doped semiconductor transport layer for use in an electronic device includes: growing a first set of semiconductor nanoparticles having surface organic ligands in a colloidal solution; growing a second set of dopant material nanoparticles having surface organic ligands in a colloidal solution; depositing a mixture of the first set of semiconductor nanoparticles and the second set of dopant material nanoparticles on a surface, wherein there are more semiconductor nanoparticles than dopant material nanoparticles; performing a first anneal of the deposited mixture of nanoparticles so that the organic ligands boil off the surfaces of the first and second set of nanoparticles; performing a second anneal of the deposited mixture so that the semiconductor nanoparticles fuse to form a continuous semiconductor layer and the dopant material atoms diffuse out from the dopant material nanoparticles and into the continuous semiconductor layer.
