Published: Control of Mg content and carrier concentration for Sb-doped Mg2Si

Our paper entitled “Control of Mg Content and Carrier Concentration via Post Annealing under Different Mg Partial Pressures for Sb-doped Mg2Si Thermoelectric Material” has been published in J. Solid State Chem. The annealing process under high Mg partial pressure is an effective way to recover the thermoelectric performance of Mg-deficient Mg2Si-based materials.

Published: Charge screening strategy for ferroelectric domain pattern control

Our paper entitled “Charge Screening Strategy for Domain Pattern Control in Nano-scale Ferroelectric Systems” has been published in Scientific Reports. We experimentally and theoretically demonstrated that the domain pattern in ferroelectric nanorods can be controlled by the charge screening state.

Published: Indirect measurements of electrocaloric effect in ferroelectric films by PUND method

Our paper entitled “Indirect Measurements of Electrocaloric Effect in Ferroelectric Thin Films by Positive-up-negative-down Method” has been published in J. Ceram. Soc. Jpn. PUND polarization measurement was employed to indirectly estimate the electrocaloric effect in ferroelectric films. By subtracting the conductive component from the observed charge profile, the electrocaloric effect was precisely determined.
