Stability: Cooling materials to cryogenic temperatures can reduce thermal noise, thereby enhancing the stability and precision of nano-scale measurements. Preservation: It helps in preserving the structural integrity of sensitive nanomaterials, which might otherwise degrade or react at higher temperatures. Quantum Effects: Many quantum effects become observable only at cryogenic temperatures, providing insights into quantum computing and other advanced fields. Material Properties: The mechanical, electrical, and thermal properties of materials often change at low temperatures, offering new avenues for material science research.
