Role of theory in the design of semiconducting nanostructures

摘要: Understanding the structure–property relationship in semiconducting nanostructures is key to tailoring technologically important physical properties and can lead design of new nanostructured materials. Examples include optoelectronic devices ranging from solar cells, novel lasers, optical amplifiers representations a quantum bit, or single polarized photon sources emitting bits. The complexity problem reflected fact that these nano-systems contain >104 atoms, suggesting an extremely large phase space sizes, shapes, constituent In this paper, we will (i) show how establish between structure nanostructures; (ii) discuss role theory with targeted properties, including review limitations typically employed methods for electronic calculations; (iii) possibilities use predictive “guide” nanostructures' fabrication; (iv) address application renewable energy issues single-photon sources.
