To gauge the performance of thermoelectric devices, scientists employ the dimensionless figure of merit, denoted as ZT. This critical metric is calculated using the relations between the Seebeck coefficient, electrical conductivity, and thermal conductivity, expressed in the formula ZT = (S2σ/κ)T. High-performing thermoelectrics are expected to feature substantial Seebeck coefficients (to create significant voltage), elevated electrical conductivity (to minimize resistive heating), and low thermal conductivity (to cultivate a pronounced temperature gradient). The intricate relationships among these properties create significant challenges due to the tight phonon-electron coupling inherent within thermoelectric systems, making the optimization process a complex endeavor.

Despite the emergence of novel thermoelectric materials, bismuth telluride (Bi2Te3)-based alloys have remained the gold standard, predominantly in commercial thermoelectric applications. The recent advancements in p-type materials, particularly (Bi,Sb)2Te3 (BST), have exhibited stable room-temperature ZT values of approximately 1.0 or more. Conversely, the development of the n-type variant, Bi2(Te,Se)3 (BTS), has lagged, largely due to production challenges associated with existing methods. Commercially available n-type BTS materials, predominantly grown using zone melting techniques, struggle with production complexities such as grain boundary separations, leading to increased manufacturing costs and compromised device performance.

To bolster the thermoelectric efficacy and mechanical resilience of n-type BTS materials, researchers have recently turned to innovative optimization strategies. This study adopts a novel approach combining lattice plainification and band engineering, facilitating the introduction of trace copper (Cu) into standard n-type BTS materials. This technique ushers in the potential to finely modulate intrinsic lattice defects and tune the conduction band structure effectively, significantly boosting carrier mobility.

The process begins with the incorporation of Cu atoms into the elemental lattice. When Cu integrates into the Bi2Te3 lattice, it occupies vacant sites, specifically Bi vacancies, thus considerably mitigating point defect scattering that can impede carrier movement. Additionally, when Cu substitutes Bi atoms within the lattice, it further influences the band structure by promoting a phenomenon known as band sharpening, effectively enhancing the conduction pathways and decreasing the effective mass of charge carriers. This dual strategy of utilizing Cu both at vacant sites and within the Bi positions enables a pronounced improvement in carrier mobility, a critical element for enhancing thermoelectric performance.

The synergistic approach of incorporating Cu delivers tangible results; the BTS samples infused with 0.2% Cu demonstrate striking improvements in key performance indicators. The measured carrier mobility reached an impressive ~285 cm2 V−1 s−1, paired with a power factor of approximately 60 μW cm−1 K−2 at room temperature. These advancements culminate in a room-temperature ZT value close to ~1.3, with an average ZT of ~1.2 over a temperature spectrum spanning 300–523 K. Importantly, the introduction of Cu also fortifies the mechanical processing attributes of the BTS+0.2%Cu crystal ingots, streamlining their production for commercial applications.

The effectiveness of these enhancements extends to the practical deployment of thermoelectric devices. Testing reveals that full-scale devices derived from the optimized BTS+0.2%Cu crystal structure, in conjunction with conventional p-type BST materials, achieve notable efficiency in power generation. Specifically, the devices exhibit an efficiency rating of approximately 6.4% under a temperature differential of 223 K, alongside an impressive maximum cooling temperature difference of ~70.1 K at ambient room temperatures.

Overall, this study sheds light on the intricate roles that trace amounts of Cu atoms play in modifying both the thermoelectric performance and the mechanical integrity of n-type BTS materials. The findings not only pave the way for enhancing the efficiency and application of Bi2Te3-based thermoelectric devices in energy generation and cooling systems but also underscore the importance of meticulous materials engineering in the ever-evolving field of thermoelectric technology.

As we continue to explore the potential of advanced thermoelectric materials, the insights gained from this research will be instrumental in propelling the practical implementation of thermoelectric solutions, ultimately fostering innovations in sustainable energy and precision temperature control. The future of thermoelectric technology appears promising, with ongoing investigations poised to unlock greater performance efficiencies and broaden its applications in diverse sectors, championing the cause of green energy alternatives.
