Abstract: A method includes at least partially submerging a substrate in a colloidal mixture of nanocrystals and a first solvent. The nanocrystals have first ligands coupled thereto. The method also includes applying an electric field to the colloidal mixture to form a solvated nanocrystal film and removing the solvated nanocrystal film from the first solvent. The method further includes applying a second solvent to the solvated nanocrystal film for ligand exchange. The second solvent comprises second ligands. A nanocrystal film product formed by one-step ligand exchange includes at least one dimension greater than 100 nm and ordered nanocrystals characterized as having a domain size of greater than 100 nm.

Abstract: A method for enhancing the equilibrium solubility of boron ad indium in silicon. The method involves first-principles quantum mechanical calculations to determine the temperature dependence of the equilibrium solubility of two important p-type dopants in silicon, namely boron and indium, under various strain conditions. The equilibrium thermodynamic solubility of size-mismatched impurities, such as boron and indium in silicon, can be raised significantly if the silicon substrate is strained appropriately. For example, for boron, a 1% compressive strain raises the equilibrium solubility by 100% at 1100° C.; and for indium, a 1% tensile strain at 1100° C., corresponds to an enhancement of the solubility by 200%.

Abstract: A method for enhancing the equilibrium solid solubility of dopants in silicon, germanium and silicon-germanium alloys. The method involves subjecting silicon-based substrate to biaxial or compression strain. It has been determined that boron solubility was largely enhanced (more than 100%) by a compressive bi-axial strain, based on a size-mismatch theory since the boron atoms are smaller than the silicon atoms. It has been found that the large enhancement or mixing properties of dopants in silicon and germanium substrates is primarily governed by their, and to second order by their size-mismatch with the substrate. Further, it has been determined that the dopant solubility enhancement with strain is most effective when the charge and the size-mismatch of the impurity favor the same type of strain. Thus, the solid solubility of small p-type (e.g., boron) as well as large n-type (e.g.
