Abstract: Methods for fabrication of copper delafossite materials include a low temperature sol-gel process for synthesizing CuBO2 powders, and a pulsed laser deposition (PLD) process for forming thin films of CuBO2, using targets made of the CuBO2 powders. The CuBO2 thin films are optically transparent p-type semiconductor oxide thin films. Devices with CuBO2 thin films include p-type transparent thin film transistors (TTFT) comprising thin film CuBO2 as a channel layer and thin film solar cells with CuBO2 p-layers. Solid state dye sensitized solar cells (SS-DSSC) comprising CuBO2 in various forms, including “core-shell” and “nano-couple” particles, and methods of manufacture, are also described.

Abstract: A system-on-chip integrated circuit selectively gates clocks to individual modules corresponding to the state of a corresponding bit of a peripheral enable register. A reset circuit supplies a signal to a reset input of the digital module for a normal mode if the bit indicates the power-up state and a reset mode if the bit indicates a power-down state. Return to normal mode is delayed a predetermined time after the said bit of indicates the power-up state to ensure clean power up. A false acknowledge circuit for each module supplies an acknowledge signal in response to a received command if the corresponding bit indicates the power-down state.

Abstract translation: 片上系统集成电路有选择地将时钟门控地对应于外围使能寄存器的相应位的状态。 如果位指示上电状态，则复位电路将信号提供给数字模块的复位输入，如果该位指示掉电状态，则将该信号提供给正常模式的复位输入。 在所述位指示上电状态之后，恢复正常模式被延迟预定时间，以确保清洁上电。 如果相应的位指示掉电状态，则每个模块的错误确认电路响应于接收到的命令提供确认信号。
