Phys.org  March 31, 2022 While analyzing the structure and optical properties of a common lead-halide hybrid perovskite an international team of researchers (USA – North Caroline State University, France) noticed the formation of polarons in these materials. Their analysis showed that formation of large polarons creates a thermal vibrational noise filter mechanism that they called ‘Quantum Analog of Vibration Isolation,’ or QAVI, which is like a shock absorber protecting the dipoles. When they are protected by the shock absorbers, the dipoles can synchronize and exhibit superfluorescence. According to the researchers, QAVI is an intrinsic property that exists in certain materials, […]
