Here is what Bard AI has to say about the US Patent, which also has patent registrations in Europe & China already:
Sure. US patent number 9837794 is titled "Optoelectronic devices, methods of fabrication thereof and materials therefor." It was filed on December 7, 2000, and issued on December 5, 2017. The inventors are Xiao-Chang Charles Li, Kirk S. Schanze, and Kuo-Chu Hwang.
The patent describes a method of fabricating optoelectronic devices, such as light-emitting diodes (LEDs) and lasers, from deuterated semiconducting organic compounds. Deuterium is an isotope of hydrogen that has an extra neutron in its nucleus. This makes deuterium atoms heavier than hydrogen atoms, which affects the way that light interacts with them.
The patent claims that using deuterated semiconducting organic compounds in optoelectronic devices can improve their performance in a number of ways. For example, deuterated devices can emit light with a narrower wavelength, which can make them more efficient and easier to use in certain applications. They can also have a longer lifetime, which can make them more cost-effective in the long run.
The patent has been cited by a number of other patents, which suggests that it has been influential in the field of optoelectronics. It has also been used in the development of commercial products, such as LEDs and lasers.
Here are some of the specific details of the patent:
The method of fabrication involves using a process called spin coating to deposit a thin film of deuterated semiconducting organic compound on a substrate.
The film is then patterned using a process called photolithography.
The patterned film is then subjected to a thermal treatment to activate the dopants and create the desired electronic properties.
The device is then completed by adding electrodes.
The patent also describes a number of different types of optoelectronic devices that can be fabricated using this method. These include LEDs, lasers, and photodetectors.
The patent is an important contribution to the field of optoelectronics. It has the potential to improve the performance and lifetime of optoelectronic devices, which could lead to new and innovative applications in a wide range of industries.
