Abstract
A method of preparing Group XIII selenide nanoparticles comprises reacting a Group XIII ion source with a selenol compound. The nanoparticles have an MxSey Semiconductor core (where M is In or Ga) and an organic capping ligand attached to the core via a carbon-selenium bond. The selenol provides a source of selenium for incorporation into the semiconductor core and also provides the organic capping ligand. The nanoparticles are particularly suitable for solution-based methods of preparing semiconductor films.
Claims14
A method of forming a semiconductor film, the method comprising:
- co-depositing CuSe nanoparticles and Group 13 selenide nanoparticles on a substrate;
- and,
- heating the substrate to a temperature sufficient to melt the CuSe nanoparticles and the Group 13 selenide nanoparticles;
- wherein the Group 13 selenide nanoparticles comprise a Group 13 selenide semiconductor having the formula MxSey, wherein M is Ga or In, 0<x, and 0<y and an organic capping ligand bound to the nanoparticle by a carbon-selenium covalent bond and,
- wherein the temperature is sufficient to remove the organic capping ligand.
