AC-frequency switchable correlated transports in rare-earth perovskite nickelates
Jikun Chen, Haifan Li, Jiaou Wang +6
Whilst electron correlations were previously recognized to trigger beyond conventional direct current (DC) electronic transportations (e.g. metal-to-insulator transitions, bad meta…
Overlooked transportation anisotropies in d-band correlated rare-earth perovskite nickelates
Jikun Chen, Haiyang Hu, Fanqi Meng +7
Anisotropies in electronic transportations conventionally originate from the nature of low symmetries in crystal structures, and were not anticipated for perovskite oxides, the cry…
Entropy driven reverse-metal-to-insulator transition and delta-temperatural transports in metastable perovskites of correlated rare-earth nickelate
Jikun Chen, Haiyang Hu, Takeaki Yajima +5
The metal to insulator transition (MIT) in Mott-Hubbard systems is one of the most important discoveries in condensed matter physics, and results in abrupt orbital transitions from…
Porosity-mediated High-performance Thermoelectric Materials
Xiaoxi Chen, Siyi Chang, Jin Chen +14
Whether porosity can effectively improve thermoelectric performance is still an open question. Herein we report that thermoelectric performance can be significantly enhanced by cre…
A micrometer-thick oxide film with high thermoelectric performance at temperature ranging from 20-400 K
Jikun Chen, Hongyi Chen, Feng Hao +12
Thermoelectric (TE) materials achieve localised conversion between thermal and electric energies, and the conversion efficiency is determined by a figure of merit zT. Up to date, t…
