Summary: This study investigates the electromechanical fields in a sandwich plate with a flexoelectric semiconductor layer between two piezomagnetic dielectric layers under a transverse magnetic field. Two-dimensional equations for the plate bending are derived from the macroscopic theory of piezomagnetics and flexoelectric semiconductors. Several solutions are obtained for static and time-harmonic magnetic loadings. Different magnetic fields can generate various distributions of mobile charges and electric fields, which is fundamental in flexotronics. In the case of pure bending under a uniform magnetic field, a coefficient is identified to characterize the strength of the interaction between the applied magnetic field and the mobile charges, which reaches its maximum at a specific thickness ratio between the two types of material layers. The frequency dependence of the coupling coefficient in time-harmonic motions is also determined.

Summary: A novel asymmetric beam-like semiconductor made of functionally graded flexoelectric materials can generate a relatively large inhomogeneous strain field under pure bending loads, achieving obvious semiconducting behaviors. The electromechanical coupling performances of this device heavily depend on the ratio and structural distributions of its constituent, as well as the strain gradient elasticity, flexoelectricity, and structural size. This study provides a useful guideline for designing and manufacturing novel electromechanical semiconductor devices.

Summary: A coupling model is established to investigate the effect of base region on device performance and the interaction between E/B and B/C in PS-BJT subjected to mechanical loadings. It is found that a too small base width results in the extraction of electrons directly from the emitter region by B/C, leading to the excitation of an electron passageway (EP-CE). This current produced by EP-CE is independent of electron-hole recombination in E/B and cannot be reckoned in the amplification effect of base current. It is revealed that the base width should not be designed too small to avoid EP-CE. The tuning of PS-BJT performance by mechanical loadings can be achieved by raising electron-hole recombination rate, elevating electron conductivity in the base region, and promoting the attractive ability of B/C on electrons.

Summary: The concept of disorder-free localization as a mechanism for ergodicity breaking in low-dimensional homogeneous lattice gauge theories is introduced in this study. Surprisingly, nonergodic behavior can also be observed in genuinely interacting systems in two spatial dimensions due to this mechanism. Furthermore, the study shows that the gauge invariance can act as an alternative robust localization mechanism surviving in higher dimensions in the presence of interactions.

Summary: In this study, the temperature effects on mobile charges in a thermopiezoelectric semiconductor plate were investigated through pyroelectric and thermoelastic couplings. A set of two-dimensional equations for extension and bending of the plate were derived using macroscopic theory. Numerical results showed that the distribution of mobile charges can be manipulated by the temperature field. The strength of the coupling between the temperature field and mobile charge distribution was characterized by identifying a combination of physical parameters.

Summary: This study investigates the properties of spin and valley transport in piezotronics valley transistors based on a normal/ferromagnetic/normal (NFN) structure of monolayer transition metal dichalcogenides (TMDs). The Rabi frequency can reach up to 4200 MHz using the piezotronics effect, which is about 1000 times higher than that of ZnO/CdO quantum well devices. The strain-induced strong polarization allows for control of the spin and valley transport properties in piezo-phototronic transistors. The theoretical calculations include the spin and valley conductance as well as the spin and valley polarizability. The strong polarization can be used to manipulate the valley qubit, thereby paving a new way for quantum computing applications based on piezotronic valley transistors.

Summary: This article introduces the use of strain-induced polarization to enhance the performance of piezoelectric solar cells. Nonuniform strain can effectively increase the piezoelectric polarization, improving the power-conversion efficiency (PCE) of piezoelectric solar cells. By strain-induced polarization, the PCEs of solar cells based on 2D WS2 and MoS2 are boosted to 48.1% and 42.8%, respectively. Strain-induced polarization not only increases the built-in field, but also simplifies bandgap gradients through inexpensive strain regulation. In this article, a tandem and parallel piezo-phototronic solar cell with single-type 2D piezoelectric semiconductor materials is proposed, providing a novel way to develop an ultrahigh efficiency 2D material solar cell.
