  • Patent number: 11973163
    Abstract: A light emitting device includes an epitaxial structure and first and second electrodes on a side of the epitaxial structure. The epitaxial structure includes a first-type semiconductor layer, an active layer, and a second-type semiconductor layer. The active layer is disposed between the first-type semiconductor layer and the second-type semiconductor layer. The first electrode is disposed on the epitaxial structure to be electrically connected with the first-type semiconductor layer. The second electrode is disposed on the epitaxial structure to be electrically connected with the second-type semiconductor layer. The second electrode is in ohmic contact with a second-type window sublayer of the second-type semiconductor layer.

  • Publication number: 20240073808
    Abstract: A cell selection method includes receiving, by an access stratum (AS) of a terminal device, first information from a non-access stratum (NAS) of the terminal device. The first information includes identity information of a first public land mobile network (PLMN) to be accessed by the terminal device. The cell selection method also includes determining, by the AS based on the first information, whether to camp on a first candidate cell. The first candidate cell supports the first PLMN. The first candidate cell satisfies a first camping condition. The first camping condition comprises a cell selection criterion and a service requirement. The service requirement is a preset threshold of a parameter reflecting signal quality of a cell.

  • Publication number: 20240034930
    Abstract: This application relates to a patterning material, a patterning composition, and a pattern forming method. The patterning material in this application includes a metal-oxygen cluster framework, a radiation-sensitive organic ligand, and a second ligand. The radiation-sensitive organic ligand coordinates with a metal M through a coordination atom. The coordination atom is at least one of: an oxygen atom, a sulfur atom, a selenium atom, a nitrogen atom, or a phosphorus atom. The radiation-sensitive organic ligand is a monodentate ligand or a polydentate ligand with a denticity of two or more. The second ligand is an inorganic ion or a coordination group.
