In the domain of nanotechnology, where device dimensions are scaled down to the nanometer range, variability and leakage current become significant issues. ABB helps mitigate these problems by providing a method to adjust the threshold voltage on-the-fly. This adaptability is crucial for maintaining device reliability and performance as process variations become more pronounced at smaller scales. Additionally, ABB enables better thermal management and power efficiency, which are critical in densely packed nanotechnological devices.
