主　　题：tunable thermal switch 

摘      要：The high-performance,wide-range tunable thermal switches play a significant role in the thermal management,high-power-density intelligent devices,energy systems,***,traditional thermal switch components,such as thermal diodes,suffer from poor stability,small adjustability,low time efficiency,and difficult ***,we propose the superior electric-controlled thermal switch(ECTS)based on Janus monolayer *** high-effective and asymmetric regulation of the thermal conductivity driven by electric field demonstrates a wide-range adjustable thermal switch ratio,where the peak value reaches 2.09 under the electric field of 0.04 VÅ^(−1).The underlying mechanism is revealed by electronic structures that the interactions between electrons and phonons are renormalized due to the electric field driving charge density redistribution,which ultimately modulates the phonon *** high-efficiency adjustable ECTS component is expected to provide new inspiration for next-generation thermal management and information processing.
