Reversible Photomodulation of Two-Dimensional Electron Gas in LaAlO/SrTiO Heterostructures.

Long-lived photoinduced conductance changes in LaAlO/SrTiO (LAO/STO) heterostructures enable their use in optoelectronic memory applications. However, it remains challenging to quench the persistent photoconductivity (PPC) instantly and reproducibly, which limits the reversible optoelectronic switching. Herein, we demonstrate a reversible photomodulation of two-dimensional electron gas (2DEG) in LAO/STO heterostructures with high reproducibility.

Collective Control of Potential-Constrained Oxygen Vacancies in Oxide Heterostructures for Gradual Resistive Switching.

Filamentary resistive switching in oxides is one of the key strategies for developing next-generation non-volatile memory devices. However, despite numerous advantages, their practical applications in neuromorphic computing are still limited due to non-uniform and indeterministic switching behavior. Given the inherent stochasticity of point defect migration, the pursuit of reliable switching likely demands an innovative approach.

Strong Interfacial Charge Trapping in Ultrathin SrRuO on SrTiO Probed by Noise Spectroscopy.

SrRuO (SRO) has emerged as a promising quantum material due to its exotic electron correlations and topological properties. In epitaxial SRO films, electron scattering against lattice phonons or defects has been considered as only a predominant mechanism accounting for electronic properties. Although the charge trapping by polar defects can also strongly influence the electronic behavior, it has often been neglected.

Variance-aware weight quantization of multi-level resistive switching devices based on Pt/LaAlO/SrTiO heterostructures.

Resistive switching devices have been regarded as a promising candidate of multi-bit memristors for synaptic applications. The key functionality of the memristors is to realize multiple non-volatile conductance states with high precision. However, the variation of device conductance inevitably causes the state-overlap issue, limiting the number of available states.

Hot Electron Tunneling in Pt/LaAlO/SrTiO Heterostructures for Enhanced Photodetection.

LaAlO/SrTiO (LAO/STO) heterostructures, in which a highly mobile two-dimensional electron gas (2DEG) is formed, have great potential for optoelectronic applications. However, the inherently high density of the 2DEG hinders the observation of photo-excitation effects in oxide heterostructures. Herein, a strong photoresponse of the 2DEG in a Pt/LAO/STO heterostructure is achieved by adopting a vertical tunneling configuration.

The combined effects of physical exercise training and detraining on adiponectin in overweight and obese children.

Background: The purpose of this study is to assess the combined exercise programs (12 weeks' physical exercise training, resistance and aerobic) and 6 weeks' detraining on the correlation of metabolic syndrome (MS) markers and plasma adiponectin level in two groups.

Methods: Participants were divided into two groups [physical exercise training group (EG,  = 8) and control group (CG,  = 7)]. The EG performed a 12-week training program (aerobic and resistance training twice/wk, more than 40 min/d).
