“…These structures exhibit rich dynamical phenomena, have exquisite sensitivity near instabilities and allow for efficient control of deformed configuration using external fields. Collectively, these aspects give rise to a myriad of functional advantages in applications such as switches 1,2 , sensors 3,4 and non-volatile memories 5 . The most common and widely used bistable element is a curved beam, shown in Fig.…”

We demonstrate dynamic snap-through from a primary to a secondary statically inaccessible stable configuration in single crystal silicon, curved, doubly clamped micromechanical beam structures. Nanoscale motion of the fabricated bistable micromechanical devices was transduced using a high speed camera. Our experimental and theoretical results collectively show, that the transition between the two stable states was solely achieved by a tailored time dependent electrostatic actuation. Fast imaging of micromechanical motion allowed for direct visualization of dynamic trapping at the statically inaccessible state. These results further suggest that our direct dynamic actuation transcends prevalent limitations in controlling geometrically non-linear microstructures, and may have applications extending to multi-stable, topologically optimized micromechanical logic and non-volatile memory architectures.

“…By controlling these switches maintained by some rules, we have the provision of release light-paths towards the destination [54]. Also MEMS is very light and suitable for operation in harsh environment of engines and inside nuclear reactors or in space applications [55][56][57][58]. It has been proved that MEMS with Si-CMOS enables a new low cost high performance nano-electromechanical device recently [59].…”

“…Such logic gates as NOT, NAND, NOR, and XOR are the main building blocks of logical functions [1], [2]. Considering these gates, the XOR gate plays a significant role in computational processors with low-power purposes and arithmetic circuits [3], [4], such as full adder cells [5], [6]-[8], parity bit generators and parity checkers [9], multipliers such as the polynomial basis multiplier [10], and comparator circuits [8], [11], [12].

The integration of digital circuits has a tight relation with the scaling down of silicon technology. The continuous scaling down of the feature size of CMOS devices enters the nanoscale, which results in such destructive effects as short channel effects. Consequently, efforts to replace silicon technology with efficient substitutes have been made. The carbon nanotube fieldeffect transistor (CNTFET) is one of the most promising replacements for this purpose because of its essential characteristics. Various digital CNTFET-based circuits, such as standard logic cells, have been designed and the results demonstrate improvements in the delay and energy consumption of these circuits. In this paper, a new CNTFET-based 5-input XOR gate based on a novel design method is proposed and simulated using the HSPICE tool based on the compact SPICE model for the CNTFET at the 32-nm technology node. The proposed method leads to improvements in performance and device count compared to the conventional CMOS-style design.Keywords: Nanotechnology, carbon nanotube fieldeffect transistor, CNTFET, high-performance circuits, CNTFET-based inverter, exclusive-OR gate, XOR gate.

I. IntroductionNo one can imagine today's world without the influence and power of computer technology, which dominates many aspects of people's lives, from such simple details as cell phones to such important and critical projects as those in aeronautics. All computer-based technological improvements are possible through computational functions, which are made up of precise logic gates. Such logic gates as NOT, NAND, NOR, and XOR are the main building blocks of logical functions [1], [2]. Considering these gates, the XOR gate plays a significant role in computational processors with low-power purposes and arithmetic circuits [3], [4], such as full adder cells [5], [6]-[8], parity bit generators and parity checkers [9], multipliers such as the polynomial basis multiplier [10], and comparator circuits [8], [11], [12]. High-speed XOR gates are needed for summation of partial products in multiplier circuits, and they are also used in MUX modules in arithmetic circuits [12].The most famous application of the XOR gate is in coding processes and data encryption or decryption, especially in AES (Advanced Encryption Standard) [1], which is sufficiently used in data communication. In design testing, it is used in built-in self-test structures [...
