Contract Opportunity

Opportunity:

Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its Simple, Cost-Effective Method for Producing Functional Electro-Optical Materials and Devices.

Background:

There is a general need for strategies to fabricate functional devices with tailored properties for specific applications at low cost; optical applications include deep UV photodetectors, flexible or wearable sensors, tunable flat optics including optical phase plates and Fresnel lenses with high laser damage performance.

Description:

LLNL researchers developed a novel strategy that involves material transformations such as oxidation, nitridation, or carbonization. In one embodiment, copper is heated under ambient conditions resulting in its surface being oxidized and turned into copper oxide, where a new material (e.g., copper oxide) is developed via transformation (e.g., oxidation) without additional addition deposition step. As a result, multiple materials can be generated without needing multiple deposition processes. For instance, two different types of copper oxide (e.g., Cu2O and CuO2) can be selectively obtained from copper by controlling the oxidation conditions.

Advantages/Benefits:

• Allows functional devices to be fabricated very simply and cost-effectively by laser-induced oxidation transformation.


• Capability to design targeted materials with designed height profile can open up a broad range of never-before considered applications.


• Transformed materials have distinctive properties (e.g., electrical, optical, chemical) from their host material.

Potential Applications:

• Transform electrically conductive metals into semiconducting oxides with tailored electrical properties yielding a photodetector in a single transformation step without multiple lithography and deposition steps.


• Produce optical phase plates in a single transformation step instead of the usual process of multiple lithography process steps.


• Design optical filters with spatially changing transmission profiles by selectively transforming optically opaque materials into optically transparent ones.

Development Status:

Current stage of technology development: TRL 2-3
