要約

Phononic (thermal) devices such as thermal diode, thermal transistors, thermal logic gates, and thermal memories have been studied intensively. However, tunable thermal resistors have not been demonstrated yet. Here, we propose an instantaneously adjustable thermal resistor based on folded graphene. Through theoretical analysis and molecular dynamics simulations, we study the phonon-folding scattering effect and the dependence of thermal resistivity on the length between two folds and the overall length. Further, we discuss the possibility to realize the instantaneously adjustable thermal resistor in experiment. Our studies bring new insights in designing thermal resistor and understanding thermal modulation of 2D materials by adjusting its basic structure parameters.
