To provide a sponsored story unit, the social networking system receives a story request from an advertiser. The story request specifies properties of content used to generate the sponsored story. When the social networking system stores an object or an action performed on an object, properties associated with, and describing, the object or the action are also stored. For example, properties of an object include an object type, an object identifier, metadata describing the object or other suitable information. The social networking system identifies actions or objects associated with users connected to a viewing user having one or more properties included in a story request. A sponsored story is generated from the identified actions or objects and presented to a viewing user.
摘要:
Solar cell structures include stacked layers in reverse order on a germanium substrate wherein a n++ (In)GaAs buffer layer plays dual roles as buffer and contact layers in the inverted structures. The absorbing layers employed in such exemplary structures are III-V layers such as (In)GaAs. Controlled spalling may be employed as part of the fabrication process for the solar cell structures, which may be single or multi-junction. The requirement for etching a buffer layer is eliminated, thereby facilitating the manufacturing process of devices using the disclosed structures.
摘要:
A stressor layer used in a controlled spalling method is removed through the use of a cleave layer that can be fractured or dissolved. The cleave layer is formed between a host semiconductor substrate and the metal stressor layer. A controlled spalling process separates a relatively thin residual host substrate layer from the host substrate. Following attachment of a handle substrate to the residual substrate layer or other layers subsequently formed thereon, the cleave layer is dissolved or otherwise compromised to facilitate removal of the stressor layer. Such removal allows the fabrication of a bifacial solar cell.
摘要:
A multilayered stack including alternating layers of sacrificial material layers and semiconductor material layers is formed on a base substrate. The thickness of each sacrificial material layer of the stack increases upwards from the sacrificial material layer that is formed nearest to the base substrate. Because of this difference in thicknesses, each sacrificial material layer etches at different rates, with thicker sacrificial material layers etching faster than thinner sacrificial material layers. An etch is performed that first removes the thickest sacrificial material layer of the multilayered stack. The uppermost semiconductor device layer within the multilayered stack is accordingly first released. As the etch continues, the other sacrificial material layers are removed sequentially, in the order of decreasing thickness, and the other semiconductor device layers are removed sequentially.
