“…In addition, graphene possesses a low mass density of 2200 kg/m 3 , comparable to silicon, which is advantageous for creating suspended structures that can be utilized to sense pressure [3] or biological elements [4]. Additional applications of graphene include the field of photodetectors [5] and spintronics [6]. For MEMS devices, recent research that has been reported suggests the utilization of graphene in accelerometers [7] and has demonstrated a flow sensor with a graphene diaphragm [8].…”

We fabricate a MEMS microphone that incorporates a graphene-based membrane that vibrates in response to acoustic forcing. We employ a novel fabrication process, where a graphene/PMMA bilayer membrane is transferred over a cavity on a separate chip before being affixed to the surface of another chip containing an electrode, resulting in the fabrication of a moveable capacitor with a membrane-to-electrode gap of 8 µm. The gap, which is less than half the size of other reported graphene membrane-based audio transducers, allows for the device to operate with low DC bias voltages of about 1 V and, when integrated with a custom-designed readout circuit, demonstrates a sensitivity to sound pressure between 0.1 mV/Pa and 10 mV/Pa across the range 100 Hz to 20 kHz. As well as a sensitivity that is comparable to previous work, the flat frequency response is stable when the sound pressure is varied between 70 dB SPL and 80 dB SPL , with the sensitivity value not varying by more than 0.2 mV/Pa.

“…As manufactures approach the limits of complementary metal oxide semiconductor (CMOS) technology, such as size limitation, high-power consumption, short-circuit effects, and high-noise absorption, new alternative technologies are being widely researched, such as single electron transistors, spintronics, and carbon-based transistors, among others [1][2][3][4][5][6]. The quantum-dot cellular automata (QCA) is a promising new paradigm.…”

This study describes the first Gray-code adder architecture, without the need to transform the Gray code into binary code, using the quantum-dot cellular automata (QCA). This device is a widely used resource for machine communications, counters, and encoders. QCA is a possible alternative to the current integrated circuit [complementary metal oxide semiconductor (CMOS)] due to its nanometric scale and very low-power consumption. In a bottom-up approach, the authors first describe and present the architecture of an important building block that composes the Gray-code adder, the parity generator, and then describe the full architecture. Besides being essential in the proposed adder, the parity generator is also important for error-checking and construction of other devices and widely used in communications. They demonstrate the functionality, test, and validate the proposed architectures using the QCADesigner simulator. If QCA consolidates as a possible CMOS substitute, this study can impact the design of future components that uses Gray-code and parity generator, such as embedded digital communications systems that will benefit from the low-power consumption of the QCA technology.

“…The research on new materials and new technologies has become a hot topic in the world. Graphene has attracted considerable attention in different fields in recent years [6][7][8][9]. It enables the frequency of the processor more than 1 THz, which is 100-000 times higher than the current silicon-based processor [10,11].…”

Graphene is regarded as an excellent substitute for silicon and an ideal chip material for the next generation of chip manufacturing. Researches show that the electrical properties of graphene are closely related to its edge structures. Graphene can exhibit metal or semiconductive characteristics according to the different edge configurations. How to fabricate graphene nanoribbons with specific edge structures is the key premise for practical applications. The review highlights the new graphene crystal orientation detection methods based on scanning probe technology, including offline detection technology and online detection technology. The advantages and disadvantages of different detection technologies are analysed, and finally, a brief outlook for the development of graphene orientation determination techniques is given.
