Abstract: Processes for laminating a conductive-lubricant coated Printed Circuit Board (PCB) are disclosed. An example laminated PCB may include a lamination stack that may further include a core, an adhesive layer, and at least one graphene-metal structure or at least one hexagonal Boron Nitride metal (h-BN-metal) structure. The materials of the PCB may change in accordance with the invention described herein, including the materials of the core, the materials of the conductive-lubricant coatings, or the metal layers of the conductive-lubricant-metal structures. Doping processes for each change in materials used are also described herein. The conductive-lubricant of the conductive-lubricant-metal structure will promote high frequency performance and heat management within the PCB. Furthermore, a removal process of those materials post-lamination is described herein to promote protection of materials and subsequent removal of protective layers without breakage or tearing.

Abstract: A light emitting device, a transmitter, and a silicon photonics chip, among other things, are disclosed. An illustrative light emitting device is disclosed to include a silicon substrate, a waveguide disposed on or integrated in the silicon substrate, where the waveguide includes a wide waveguide section at a first end and a narrow waveguide section at a second end, a first metal pad disposed over the wide waveguide section and at least partially across the first end of the waveguide, and a second metal pad disposed over the wide waveguide section, distanced away from the first metal pad. Electrical current passing between the first metal pad and the second metal pad may cause light to be produced in the wide waveguide section and the light produced in the wide waveguide section is at least partially reflected by the first metal pad and directed to the narrow waveguide section for transmission.

Abstract: Processes for creating a two-dimensional-target structure are disclosed. An example process to create a two-dimensional-target structure may include the process of providing two-dimensional material grown on an initial substrate to create a two-dimensional-substrate structure; applying the two-dimensional-substrate structure to a target substrate via an adhesion promoter to create a lamination stack; applying a lamination process to the lamination stack; and then removing the initial substrate from the lamination stack, post-lamination, to create the two-dimensional-target structure. The two-dimensional-target structure may then be used in such rigid or flexible electronic devices and/or non-standard devices as the target substrate may be rigid or flexible and/or translucent in contrast to the initial substrate first used to grow the two-dimensional material.

Abstract: Processes for localized lasering of a lamination stack and graphene-coated printed circuit board (PCB) are disclosed. An example PCB may include a lamination stack, post-lamination, that may further include a core, an adhesive layer, and at least one graphene-metal structure. A top layer of graphene of the graphene-metal structure may have never been grown before the lamination process or may have been removed post-lamination such that a portion of the top layer of graphene is missing. The localized lasering process described herein may grow (for the first time) or re-grow the graphene layer of the exposed portion of the metal layer without adverse effects to the rest of the lamination stack or PCB and while promoting a uniform layer of graphene on the top surface. A process of growing graphene through application of molecular layer and a self-assembled monolayer (SAM), are also described herein.

Abstract: Processes for laminating a graphene-coated printed circuit board (PCB) are disclosed. An example laminated PCB may include a lamination stack that may include an inner core, an adhesive layer, and at least one graphene-metal structure. Pressure and heat—which may be applied under vacuum or controlled gas atmosphere—may be applied to the lamination stack, after all materials have been placed. The graphene of the graphene-metal structure is designed to promote high frequency performance and heat management within the PCB.

Abstract: A membrane hetero-structure includes a polymer layer and a single-layer or multi-layer graphene sheet disposed on the polymer layer. The membrane hetero-structure is tensioned across a frame having an opening such that both the polymer layer and the graphene sheet extend across the opening. An optional rigid member is provided in a center of the membrane to be spaced apart from edges of the opening. The assembly of the frame and membrane hetero-structure forms an electrostatically driven micro-electro-mechanical system (MEMS) or sound generation and recording apparatus. In one instance, when a voltage signal is applied between an electrode layer parallel to the membrane and contacts on the frame that are electrically connected to the graphene sheet, the membrane hetero-structure is actuated.
