Studying Plasmaron Dynamics at Filling Factors of 1 to 2
摘要
Abstract
The authors study the photoluminescence spectra of two-dimensional electron systems in the 1 to 2 range of filling factors at a temperature of 40 mK. Plasmaron peaks and their restructuring in the spectrum are identified at a filling factor of 4/3. Additional peaks referred to as double plasmarons are detected at high pumping powers, indicating complex interactions within the system.
