Embedding FeSe monolayers within a bulk crystal for high thermoelectric performance

Caption

Material-design strategy for TlFe1.6Se2. Atomically thin FeSe layers embedded in a bulk crystal enhance the thermoelectric power, whereas ordered Fe vacancies strongly suppress thermal conductivity. Their combination enables the simultaneous realization of high thermoelectric performance and exceptionally low thermal conductivity in a practical bulk material.
