The in-plane crystalline texture of the textured layer is sufficiently low to allow growth of high quality hexagonal material, but can still be significantly greater than the required in-plane crystalline texture of the hexagonal material. The IBAD process enables low-cost, large-area, flexible metal foil substrates to be used as potential alternatives to single-crystal sapphire and silicon for manufacture of electronic devices, enabling scaled-up roll-to-roll, sheet-to-sheet, or similar fabrication processes to be used.

Electronic devices such as LEDs can be manufactured from such structures. Because the substrate can act as both a reflector and a heat sink, transfer to other substrates, and use of external reflectors and heat sinks, is not required, greatly reducing costs. Large area devices such as light emitting strips or sheets may be fabricated using this technology. |

Method and system for location-based product recommendation
A location-based product recommendation system uses consumer profile data, a network of beacons that emit unique identifiers, and a recommender to determine current product-correlated location information for a space in which a consumer's mobile device is physically present. The system may use the current product-correlated location information and the consumer's profile data to generate a recommendation for a candidate product for the consumer to consider. The system also may incorporate data from other interactions with products such as purchases, clicks on a website, etc. The system also may incorporate data generated on multiple channels (e.g., a product click on a personal computer at work, a mobile device location in a physical store, a product purchase on a personal computer in the home) into a single profile for the consumer. |
