以下の英文を読み、設問に答えなさい。

The relentless miniaturization of electronics, a hallmark of the nanotechnology revolution, has led to unprecedented advancements in computing power and device functionality. However, this progress comes at a cost. As transistors shrink to nanoscale dimensions, their energy efficiency, surprisingly, decreases. This counterintuitive phenomenon is a major obstacle in the quest for truly sustainable and energy-efficient electronics. One key reason for this energy inefficiency lies in the physics governing charge transport at the nanoscale. At such small scales, quantum mechanical effects become dominant, leading to increased leakage currents and reduced control over electron flow. These leakage currents represent a significant drain on energy, even when the device is seemingly idle. Furthermore, the intricate fabrication processes required for nanoscale devices consume substantial amounts of energy themselves, adding to the overall environmental impact. Researchers are actively pursuing various strategies to mitigate this energy problem. One approach involves exploring new materials with superior electrical properties, such as novel two-dimensional materials like graphene or transition metal dichalcogenides. These materials offer the potential for higher carrier mobility and reduced leakage currents, leading to more energy-efficient devices. Another avenue of research involves exploring new device architectures that minimize leakage currents and improve control over electron transport. For example, researchers are investigating the use of negative capacitance transistors, which can enhance the switching speed and reduce energy consumption. Careful observation at the nanoscale level is crucial in understanding and addressing these challenges. Advanced microscopy techniques, such as scanning tunneling microscopy (STM) and transmission electron microscopy (TEM), allow researchers to visualize the structure and behavior of nanoscale devices with unprecedented detail. This detailed observational data is essential for guiding the design and optimization of energy-efficient nanoscale components. Furthermore, innovative simulation tools are being developed to model the complex quantum phenomena governing nanoscale charge transport, enabling researchers to predict the energy performance of new devices before they are even fabricated. The synergy between observation, simulation, and material innovation is driving progress in energy-efficient nanotechnology. Ultimately, the quest for sustainable electronics hinges on a deep understanding of the intricate interplay between nanoscale physics, device architecture, and materials science. By combining careful observation with advanced simulations and materials innovation, researchers are paving the way for a future of truly energy-efficient and environmentally friendly electronics.
