Summary: In this study, the authors utilize the Schottky barrier at the metal/ferroelectric interface to control the self-polarization states of a ferroelectric thin film heterostructure. Through investigation and theoretical studies, they demonstrate that doping with Sm changes the concentration and distribution of oxygen vacancies, which alters the Schottky barrier and depolarization field, resulting in the evolution of the system from single domain to polydomain states. By engineering self-polarization, they also achieve significant improvement in the resistive switching behaviors of the ferroelectric diodes (FDs). This research provides insights into self-polarization and its impact on device performance, making FDs a competitive memristor candidate for neuromorphic computing.

Summary: The electrical characteristics and resistive switching properties of memristive devices using silicon oxide and titanium nitride as the insulator and electrode materials have been studied. The as-fabricated devices do not require electroforming, but their resistance state cannot be stored before thermal treatment. After the thermal treatment, the devices exhibit bipolar-type resistive switching with synaptic behavior, where filaments form in the insulator due to the effect of traps. These devices can be easily integrated with traditional analog-digital circuits to implement new-generation hardware neuromorphic systems.

Summary: Resistive switching memory (RSM) is a crucial factor for the future development of the semiconductor industry due to its advantages. However, the electrical reading of the RSM array is typically in series sequence, which limits its data storage density and processing speed. To overcome this drawback, an optically and electrically controllable light-emitting RSM has been demonstrated using a tandem structure of a light-emitting RSM and a perovskite solar cell. This device offers both electrical and optical encoding and can be read optically through electroluminescence in the low-resistive state.

Summary: Analysis of single-cell microRNA is essential for revealing genetic heterogeneity at the cell level. In this study, SERS and fluorescence imaging technology were used to achieve direct in situ, nondestructive, and highly sensitive detection of a small number of microRNA-21 (miR-21) in a single intact living cell. A multifunctional plasmonic nanoprobe was designed, allowing for highly sensitive and reliable detection of miR-21 through dual-signal switching. The combination of SERS and microdroplets encapsulation provided a feasible way to determine miR-21 secreted by single cells without cell lysis and time-consuming isolation steps. The research accurately and quantitatively evaluated the cellular heterogeneity in miR-21 expression, providing important reference information for understanding the effects of miRNAs on cancer diseases at the single-cell level.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
