mesoscopic systems

Mesoscopic systems are physical structures that are larger than atoms but small enough for quantum effects to influence their properties, typically on the scale of nanometers to micrometers. At this size, materials exhibit a mix of classical behavior, like flowing or resistivity, and quantum behaviors, such as interference or tunneling. These systems are studied in fields like nanotechnology and condensed matter physics because understanding them can lead to advanced electronic devices, sensors, and quantum computing components. Essentially, they bridge the gap between the microscopic world of atoms and the macroscopic world we experience daily.
