Latest Patents

One of Lenosky's latest patents is titled "Semiconductor material and method for enhancing solubility of a dopant therein." This innovative method focuses on enhancing the equilibrium solubility of boron and indium in silicon. By utilizing first-principles quantum mechanical calculations, Lenosky determined the temperature dependence of the equilibrium solubility of these important p-type dopants under various strain conditions. His findings indicate that the equilibrium thermodynamic solubility of size-mismatched impurities can be significantly increased with appropriate strain applied to the silicon substrate. For instance, a 1% compressive strain can raise boron's equilibrium solubility by 100% at 1100°C, while a 1% tensile strain can enhance indium's solubility by 200% at the same temperature.

Another notable patent is the "Method for enhancing the solubility of dopants in silicon." This method enhances the equilibrium solid solubility of dopants in silicon, germanium, and silicon-germanium alloys by subjecting the silicon-based substrate to biaxial or compressive strain. Lenosky's research shows that boron solubility can be significantly enhanced by a compressive bi-axial strain, based on size-mismatch theory. The findings suggest that the enhancement of dopant solubility with strain is most effective when the charge and size-mismatch of the impurity favor the same type of strain.
