We report a large and nonvolatile bipolar-electric-field-controlled magnetization at room temperature in Co(40)Fe(40)B(20)/Pb(Mg(1/3)Nb(2/3))(0.7)Ti(0.3)O(3) structure, which exhibits an electric-field-controlled looplike magnetization. Investigations on the ferroelectric domains crystal structures with situ electric fields reveal that effect is related to combined action of 109° ferroelastic domain switching absence magnetocrystalline anisotropy Co(40)Fe(40)B(20). This work provides route...
Abstract The characteristics of the soft component and ionic‐electronic nature in all‐inorganic CsPbI 3‐x Br x perovskite typically lead to a significant number halide vacancy defects ions migration, resulting reduction both photovoltaic efficiency stability. Herein, we present tailored approach which anion‐fixation undercoordinated‐Pb passivation are achieved situ during crystallization by employing molecule derived from aniline, specifically 2‐methoxy‐5‐trifluoromethylaniline (MFA),...
GeTe exhibits excellent p-type medium-temperature thermoelectric properties with low toxicity and good mechanical characteristics, making it highly promising for development in the field. However, is prone to producing Ge vacancies, leading high carrier concentration, which results elevated electronic thermal conductivity a Seebeck coefficient. This study systematically analyzes intrinsic extrinsic defects its alloys, focusing on reducing concentration through first-principles calculations....
Abstract Due to its soft lattice characteristics, all‐inorganic cesium lead halide (CsPbI 3‐x Br x ) perovskite is vulnerable external environmental stress such as moisture, polar solvent, illumination. resulting in structural defects (V I , i etc.) and ion mobility. However, most of the prior arts focus on short‐term static passivation, which has a negligible effect formed during solar cell operation. Herein, photoisomerizable molecule, 1,3,3‐trimethylindolino‐8′‐methoxybenzopyrylospiran...

Abstract Element doping/alloying is a common strategy to tune the electrical and thermal transports of thermoelectric (TE) materials, but limit foreign elements in many TE materials usually very low, bringing great challenge improve performance. In this work, beyond classic principle “like dissolves like,” it found that choosing compound with severely distorted lattice diversified chemical bonding as matrix also facilitates achieving high limit. Taking ductile semiconductors an example, work...
Large Seebeck coefficients induced by high degeneracy of conduction band minimum, and low intrinsic lattice thermal conductivity originated from large vibrational anharmonicity render Mg3Sb2 as a promising n-type thermoelectric material. Herein, we demonstrated unique concentration-dependent occupation behaviors Cu in Mg3.4Sb1.5Bi0.49Te0.01 matrix, evidenced structural characterization transport property measurements. It is found that atoms prefer to enter the interstitial sites host with...
Heterostructures were fabricated by growing Pr0.6Ca0.4MnO3 (PCMO) films on Pb(Mg1/3Nb2/3)0.7Ti0.3O3 substrates. It was shown that the magnetizations of samples can be tuned dramatically electric fields via piezostrain and effect is dominated change in phase separation. More interestingly, electric-field control magnetization nonvolatile, manifesting a memory strain. The results discussed considering electric-field-induced strain energy landscape PCMO resultant This work helpful for exploring...
