Thanks to nanoscale devices as small as human cells, researchers can create groundbreaking material properties, leading to smaller, faster, and more energy-efficient electronics. However, to fully unlock the potential of nanotechnology, addressing noise is crucial.
A research team has taken a significant step toward unraveling fundamental constraints on noise, paving the way for future nanoelectronics.
Nanotechnology is rapidly advancing, capturing widespread interest across industries such as communications and energy production. At the nano level -- equivalent to a millionth of a millimeter -- particles adhere to quantum mechanical laws. By harnessing these properties, materials can be engineered to exhibit enhanced conductivity, magnetism, and energy efficiency.
"At the nanoscale, devices can have entirely new and desirable properties. These devices, which are a hundred to ten thousand times smaller than a human cell, allow to design highly efficient energy conversion processes," says Ludovico Tesser, PhD student in Applied Quantum Physics at Chalmers University of Technology.However, noise poses a significant hurdle in advancing this nanotechnology research.
"We can prove that there is a fundamental constraint to the noise directly affecting the performance of the 'engine'. For example, we can not only see that if you want the device to produce a lot of power, you need to tolerate higher noise levels, but also the exact amount of noise. It clarifies a trade-off relation, that is how much noise one must endure to extract a specific amount of power from these nanoscale engines.
