Free-Standing Quantum Dots for Electronic Applications

摘要

Free-Standing Quantum dots (FSQdot), also known as nano-crystals, are semiconductors composed of II-VI, III-V, or IV-VI materials. Ranging in size from 2-10 nanometers in diameter, these FSQdots have size-tunable band gaps. Unlike Qdots produced on semiconductor wafers, FSQdots can be manufactured using scalable colloidal solution chemistry. These FSQdots have high photo-luminescence quantum efficiencies, good thermal and photo-stability, narrow emission line widths (atom-like spectral emission), and are compatible with solution processing. Solution processable FSQdots can be modified using innovative surface functionalization schemes. Once appropriately functionalized, the FSQdots can be incorporated into printable inks and bound to surfaces. These capabilities unlock a realm of possibilities for producing novel commercial electronic products, from unique surface coatings to new display constructions.
