Room-temperature thermoelectric materials are important for converting heat into electrical energy.As a wide-bandgap semiconductor material,CuI has the characteristics of non-toxicity,low cost,and environmental friend-liness.In this work,CuI powder was synthesized by a wet chemical method,then CuI film was formed by vacuum assisted filtration of the CuI powder on a porous nylon membrane,followed by hot pressing.The film exhibits a large Seebeck coefficient of 600 μV·K-1 at room temperature.In addition,the film also shows good flexibility(～95％ retention of the electrical conductivity after being bent along a rod with a radius of 4 mm for 1000 times).A finger touch test on a single-leg TE module indicates that a voltage of 0.9 mV was immediately generated within 0.5 s from a temperature difference of 4 K between a finger and the environment,suggesting the potential application in wearable thermal sensors.

It is known that p-type GeTe-based materials show excellent thermoelectric performance due to the favorable electronic band structure.However,n-type doping in GeTe is of challenge owing to the native Ge vacancies and high hole concentration of about 1021
In recent years,great success has been achieved on the classification of symmetry-protected topological (SPT)phases for interacting fermion systems by using generalized cohomology theory.However,the explicit calculation of generalized cohomology theory is
