ABSTRACT = {Copper selenide has emerged as a promising thermoelectric material due to its unique 
structural properties and tunable electronic band structure. However, its practical application 
is hindered by its relatively high thermal conductivity. In this study, we report on the turning 
of thermal conductivity and thermoelectric energy conversion by preparing a hybrid 
composite material including nano- and micro-sized Cu₂Se. By employing a hydrothermal 
synthesis method with cetyltrimethylammonium bromide (CTAB) as a surfactant, we 
successfully synthesized nano-sized Cu<sub>₂</sub>Se particles with uniform size distribution. The 
incorporation of these nano-sized particles with micro-sized Cu₂Se resulted in a significant 
reduction in thermal conductivity, leading to adjustment of the thermoelectric performances. 
Our findings provide a promising strategy for designing high-performance thermoelectric 
materials for waste heat recovery and energy conversion applications in the medium 
temperature range. },
