Abstract
Ballistic thermal transport properties in a cylindrical quantum structure modulated with double quantum dots (DQDs) are investigated. Results show that the transmission coefficients exhibit the irregular oscillation. Some resonant transmission peaks and stop-frequency gaps can be observed, and the number and positions of these peaks and gaps are sensitive to the sizes of DQDs. With increasing the temperature, the thermal conductance undergoes a transition from the decrease to increase, and can be efficiently tuned by modulating the radius, length of DQDs as well as the interval between DQDs. In addition, at low temperatures, the enhancement of the thermal conductance can be also observed in this case. Some similarities and differences between the cylindrical and rectangular structures are identified.
