Technology Overview
Quantum Dots: Reinventing the Semiconductor
A semiconductor is a material that conducts electricity when stimulated or, when unstimulated, is an insulator. Traditional semiconductors are the building blocks for most modern technologies, but they do have a shortcoming. They lack versatility. Their optical and electronic properties can be difficult and costly to adjust because their electronic structure can be changed only through complex manufacturing processes.
Quantum dots are different. They are semiconductor particles so small that approximately 4,000,000 quantum dots can fit across the face of a penny. At this scale the fundamental properties can be tuned or changed, overcoming many of the limitations of traditional semiconductors and opening up a world of product possibilities.
evidot® Technology
We have developed an advanced form of quantum dots - our proprietary evidot - which can be used to enable next-generation products across many markets.
- We control the size and shape of our quantum dots through the careful selection of compound semiconductors and other elements, along with atom-by-atom growth;
- We have also perfected coatings and surfaces to make our quantum dots more durable and offer better performance:
- Our proprietary quantum dot shelling methods remove surface defects;
- This adds strength to the quantum dot and prevents performance degradation;
- The engineering of the quantum dot surface also creates compatibility with a range of matrix materials, organic solvents, and water; and
- We incorporate evidot products into polymers, epoxies, silicones, sol-gels, and oxides; and
- We also link evidot products to secondary particles, molecules, and surfaces, making them compatible with common chemistries and easily used in a wide range of applications.
- We have the capability to manufacture commercial quantities of superior quality evidot quantum dots that emit from deep blue at 490 nanometers through the visible spectrum and into the infrared;
