摘　　要：Thermal metamaterials enable heat-flow manipulation alongside many emerging thermal functionalities.However,macroscale experimental performances are usually less satisfactory due to the errors of effective medium design,imprecision fabrication and the nonnegligible thermal-contact resistance.In the Nano Letters paper[1],Wu and coworkers propose the ion-write micro-thermotics(IWMT)platform,on which they overcome the issues in the macroscale and experimentally demonstrate the microscale thermal cloak and rectifier functionalities.The fundamental progress is the successful experimental demonstration of twodimensional(2D)phonon engineerings which can be applied to explore more microscale thermal functionalities and reveal more physics with newly-added spatial phonon-distribution information.To highlight the progress.
