“…Such accurate and unified model of Q is essential for understanding and optimizing the Q at relatively large vibration amplitudes and for precisely estimating many important device characteristics, such as the signal-to-noise ratio, 5,46 mass and force resolution, 2 and power consumption. 47 The results further pave the way toward high-reliability, high-performance, and low-power sensing, communication, memory, computing, and quantum engineering using 2D NEMS resonators. The 2D MoS 2 (Figure 1a) and MoTe 2 (Figure 4a) NEMS resonators are fabricated by dry-transferring the 2D materials onto the prepatterned substrate with circular microtrenches and contact electrodes.…”

In resonant nanoelectromechanical systems (NEMS), the quality (Q) factor is essential for sensing, communication, and computing applications. While a large vibrational amplitude is useful for increasing the signal-to-noise ratio, the damping in this regime is more complex because both linear and nonlinear damping are important, and an accurate model for Q has not been fully explored. Here, we demonstrate that by combining the time-domain ringdown and frequency-domain resonance measurements, we extract the accurate Q for two-dimensional (2D) MoS2 and MoTe2 NEMS resonators at different vibration amplitudes. In particular, in the transition region between linear and nonlinear damping, Q can be precisely extracted by fitting to the ringdown characteristics. By varying AC driving, we tune the Q by ΔQ/Q = 269% and extract the nonlinear damping coefficient. We develop the dissipation model that well captures the linear to nonlinear damping, providing important insights for accurately modeling and optimizing Q in 2D NEMS resonators.

“…In the quasi-static mode, structural deformations of the nanostructure are used to switch from one stability point to another, also usually employing formation of electrical and mechanical contact. This is used in logic and memory elements (switches and relays) to create fast switching suitable for harsh environment applications [2][3][4]. Dynamic NEMSs exploit their vibrations in non-contact mode.…”

A single transistor preamplifier circuit was designed to facilitate electrical detection of mechanical oscillations in nanoelectromechanical systems (NEMSs) at low temperatures. The amplifier was integrated in the close vicinity of the nanowire inside the cryostat to minimize cabling load and interference. The function of the circuit was impedance conversion for current flow measurements in NEMSs with a high internal resistance. The circuit was tested to operate at temperatures as low as 5 K and demonstrated the ability to detect oscillations in double-clamped bismuth selenide nanowires upon excitation by a 0.1 MHz–10 MHz AC signal applied to a mechanically separated gate electrode. A strong resonance frequency dependency on temperature was observed. A relatively weak shift in the oscillation amplitude and resonance frequency was measured when a DC bias voltage was applied to the gate electrode at a constant temperature.

“…However, the semiconductor industry is not without challenges. The recent chip shortage, exacerbated by the COVID-19 pandemic, has highlighted the fragility of global supply chains and the need for diversification (Frederico et al, 2023;Mzougui et al, 2023;Wang et al, 2023). In this context, it becomes important to understand the trajectory of the semiconductor industry, its current and future challenges, as well as the geopolitical implications and industrial policies adopted by different nations.…”

Semiconductor Industry, the Foundation of the Contemporary Technological Revolution, has been continuously evolving from the early transistors to today’s advanced microchips. Historically dominated by powers such as the United States, the last decade has witnessed the rise of Asia, especially China, as a vital center for production and research, reshaping the geopolitical balance of the sector. Driven by the growing demand for electronic devices and digitization, the industry faces challenges such as the recent chip shortage, exacerbated by the COVID-19 pandemic. However, emerging technologies like tunnel gate transistors, graphene, and resistive memory promise to further revolutionize the field. This narrative review provides a comprehensive analysis of the evolution of semiconductors, highlighting technological innovations, current challenges, and geopolitical implications, with a special focus on the intersection between economy and technology.
