ACS Applied Electronic Materials, Год журнала: 2024, Номер unknown

Опубликована: Дек. 3, 2024

The majority of waste heat sources are industrial steel and automobile where the operating temperature is higher than 673 K. However, development thermoelectric (TE) field still limited by low temperature, high-cost raw materials, unstable device performance. β-Ga2O3 endowed with nontoxic, eco-friendly, low-cost, thermal stability advantages, which may be a potential high-temperature oxide material. Here, capacitance–voltage (C–V) measurements phonon-dominant transport mechanism revealed at first; lower lattice conductivity will obtained test temperature. Additionally, electrical properties further demonstrated Seebeck coefficient segmented range (323∼523 K; 873∼1073 K), indicating that regulation carrier concentration effective to optimize TE maximum ZT 0.237 for sample ND = 6.1 × 1018 cm–3 1073 K, whose increase more twice another 5.7 1017 cm–3. As result, promising candidate possesses great durability in harsh environment, especially application scenarios performance equally important.
