摘      要：Ballistic thermal transport properties in a cylindrical quantum structure modulated with double quantum dots(DQDs) are *** show that the transmission coefficients exhibit the irregular *** 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 *** 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 *** addition,at low temperatures,the enhancement of the thermal conductance can be also observed in this *** similarities and differences between the cylindrical and rectangular structures are identified.
