Abstract: Systems and methods for novel uses and/or improvements to blockchains and blockchain technology. As one example, systems and methods are described herein for self-validating digital records that may be transferred in real-time through a cross-network registry. For example, in a conventional system, minting a token (e.g., a digital record) involves writing a self-executing program that defines the transfer rules of the digital record. Once the self-executing program is written, it is deployed on a blockchain, and the digital record is minted by publishing it to a blockchain.

Abstract: Light-emitting diodes (LEDs), and more particularly edge structures for light shaping in LED chips are disclosed. Edge structures may include a repeating pattern of features that is formed along one or more mesa sidewalls of active LED structure mesas. Such active LED structure mesas may include a p-type layer, an active layer, and at least a portion of an n-type layer. Features of the repeating pattern may be configured with a size and/or shape to promote redirection of laterally propagating light from the active layer at the mesa sidewalls. In this manner, light that may otherwise escape the LED chip at the mesa sidewalls may be redirected toward an intended emission direction for the LED chip. Certain aspects include reflective structures that are provided on the active LED structures mesas and are further arranged to extend past the active LED structure mesas to cover the repeating pattern of features.

Abstract: Solid-state lighting devices including light-emitting diodes (LEDs) and more particularly passivation structures for LED chips are disclosed. LED chips include active LED structures, typically formed of epitaxial semiconductor layers, that include mesas with mesa sidewalls. Passivation structures include a passivation layer that bounds the mesa sidewalls. The passivation layer includes a material that is robust to etchants of active LED structures when forming the mesas to reduce damage in underlying portions of the LED chip. The passivation layer effectively forms a seal along the mesa sidewalls that reduces unwanted undercutting or erosion during etching, thereby providing improved reliability, reduced moisture ingress, and the flexibility to enable additional chip structures, such as light extraction features.
