Abstract Triggered by the pioneering research on graphene, family of two-dimensional layered materials (2DLMs) has been investigated for more than a decade, and appealing functionalities have demonstrated. However, there are still challenges inhibiting high-quality growth circuit-level integration, results from previous studies far complying with industrial standards. Here, we overcome these utilizing machine-learning (ML) algorithms to evaluate key process parameters that impact electrical...
Abstract For strongly correlated oxides, it has been a long-standing issue regarding the role of chemical ordering dopants on physical properties. Here, using unit cell by superlattice growth technique, we determine Pr dopant in colossal magnetoresistant (La 1− y ) x Ca MnO 3 (LPCMO) system, which well known for its large length-scale electronic phase separation phenomena. Our experimental results show that leads to marked reduction length scale separations. Moreover, compared with...
Zirconia (ZrO2) ceramics have potential applications in the field of oral medicine owing to their desirable mechanical properties, biocompatibility, chemical stability, and aesthetic properties. To realize clinical applications, ZrO2(3Y)/Al2O3 bioceramics for all-ceramic dental implants were prepared using vat photopolymerization 3D printing technology, process optimization, microstructure, mechanics, tribology, biological properties studied. The results indicate that when sintering...
Two-dimensional van der Waals (2D vdW) materials have opened up an opportunity to explore innovative spin-based magnetic nanodevice. However, controllable fabrication of 2D vdW ferromagnets with high Curie temperature remains challenging. In this paper, we reported the growth CrTe2 single-crystal films epitaxially on Al2O3 substrates using pulsed laser deposition. We find that it shows a typical paramagnetic–ferromagnetic (PM–FM) phase transition around 200 K. The precise and Weiss are 189...
Electronic phase separation in complex oxides is the inhomogeneous spatial distribution of electronic phases, involving length scales much larger than those structural defects or nonuniform chemical dopants. While experimental efforts focused on and established its correlation with nonlinear responses under external stimuli, it remains controversial whether requires quenched disorder for realization. Early theory predicted that if perfectly "clean" samples could be grown, both nonlinearities...
In this Letter, we investigate the electronic structure of a spin-triplet superconductor candidate ${\mathrm{CeRh}}_{2}{\mathrm{As}}_{2}$ using high-resolution angle-resolved photoemission spectroscopy and density functional theory calculations. Notably, possible Fermi surface nesting hints at connections to magnetic excitation or quadrupole wave phenomena, elucidating superconducting mechanisms. Measured band structures reveal primarily localized $4f$ electrons, with minor itinerant...
The interaction between the metallic and superconducting components at interface of superconductor–normal metal (S-N) systems enables a variety quantum phenomena, including Josephson effect, Andreev reflection, proximity-induced superconductivity, which are significant interest both theoretically practically. Nevertheless, due to varying physical mechanisms, achieving fine-tuning multiple such phenomena within single S-N system continues be challenge. In this work, we employ NbSe2 WTe2...
A “rewritable paper” based on Ba 3 MgSi 2 O 8 inorganic photochromic material presents a series of advantages such as large contrast (77.1%), fast response time (3 s), strong fatigue resistance and stable physical/chemical properties.
At ultrafast timescales, the initial and final states of a first-order metal-insulator transition often coexist forming clusters two phases. Here, we report an unexpected third long-lived intermediate state emerging at photoinduced La_{0.325}Pr_{0.3}Ca_{0.375}MnO_{3}, known to display submicrometer length-scale phase separation. Using magnetic force microscopy time-dependent magneto-optical Kerr effect, determined that is nanoscale mixture competing ferromagnetic metallic charge-ordered...
InGaAs/AlGaAs multiple quantum well lasers grown on silicon (001) by molecular beam epitaxy have been demonstrated. By inserting InAlAs trapping layers into AlGaAs cladding layers, misfit dislocations easily located in the active region can be effectively transferred out of region. For comparison, same laser structure without was also grown. All these as-grown materials were fabricated Fabry-Perot with cavity size 20 × 1000 µm2. The achieved a 2.7-fold reduction threshold current density...
Significance Electronic phase separation (EPS) is a common phenomenon in complex oxides systems. However, little known regarding how EPS responds when the size of system smaller than characteristic EPS. This issue not only important for understanding physical origin but also device applications which have to be fabricated into small-sized structures. Our work on manganites shows surprising transition from state single spatial length scale observation paves way manipulate EPS, potentially...
Manganites are known to often show colossal electroresistance (CER) in addition magnetoresistance. The ${(\mathrm{L}{\mathrm{a}}_{1\ensuremath{-}y}\mathrm{P}{\mathrm{r}}_{y})}_{1\ensuremath{-}x}\mathrm{C}{\mathrm{a}}_{x}\mathrm{Mn}{\mathrm{O}}_{3}$ (LPCMO) system has a peculiar CER behavior that little change of magnetization occurs. We use magnetic force microscope uncover the mechanism LPCMO system. In contrast previous belief current reshapes ferromagnetic metallic (FMM) domains, we shape...
Bi2Se3 possesses a two-dimensional layered rhombohedral crystal structure, where the quintuple layers (QLs) are covalently bonded within but weakly held together by van der Waals forces between adjacent QLs. It is also pointed out that topological insulator, making it promising candidate for wide range of electronic and optoelectronic applications. In this study, we investigate growth high-quality thin films on mica molecular beam epitaxy technique. The exhibited structure highly...
We report thickness dependent inhomogeneous antiferromagnetic (AFM) to ferromagnetic (FM) phase transitions in ultrathin $\mathrm{L}{\mathrm{a}}_{0.7}\mathrm{S}{\mathrm{r}}_{0.3}\mathrm{Mn}{\mathrm{O}}_{3}$ (LSMO) films grown on the $\mathrm{SrTi}{\mathrm{O}}_{3}$ substrate. When are 4--7 unit cells (UCs) thick, FM domains appear as isolated nanodisks AFM matrix that together floats top of three base UCs, leading a superparamagnetic blocking behavior. Our first principles calculations...
