Vision-based place recognition is a desirable feature for an autonomous mobile system. In order to work in realistic scenarios, visual algorithms should be adaptive, i.e. able learn from experience and adapt continuously changes the environment. This paper presents discriminative incremental learning approach recognition. We use recently introduced version of SVM, which allows control memory requirements as system updates its internal representation. At same time, it preserves performance...
Metal halide perovskite ferroelectrics combining spontaneous polarization and excellent semiconducting properties is an ideal platform for enabling self-driven X-ray detection. However, achievements to date have been only based on uniaxiality, which increases the complexity of device fabrication. Multi-axial ferroelectric materials multiple equivalent directions, making them potentially amenable multi-axial detection, but report these types still a huge blank. Herein, high-quality (BA)
Precise stacking of distinct two‐dimensional (2D) rigid slabs to build heterostructures has renewed the portfolio 2D materials, e.g., magic‐angle graphene, due emergence exotic physical properties. Recently, single‐crystal layered perovskites have emerged as an exciting branch, while it remains scarce achieve strong ferroelectricity in this new heterostructure family. Here, we present first ferroelectric perovskite single crystal, (EA3Pb2Br7)EA4Pb3Br10 (1, EA = ethylamine), by precisely...
The remarkable FE-PV effect driven stable and self-powered X-ray detection in a green halide hybrid ferroelectric crystal [H 2 mdap]BiBr 5 with relatively high sensitivity, low limit, good stability, advancing towards safer more detection.
Spintronics has long been an exciting branch of condensed matter science, among which the spin splitting energy bands in inversion asymmetric material endows circular photogalvanic effects (CPGE) toward high‐performance spin‐based optoelectronic devices. Here, we have successfully achieved gate‐tunable CPGE a biaxial perovskite ferroelectric (n‐heptanamine)2CsPb2Br7 (1), involving broken symmetry from its spontaneous polarization. Strikingly, under left‐ and right‐circularly polarized light,...
Manipulating domain structure in ferroelectrics by external stimuli presents a fascinating avenue for new‐generation electronic devices. However, multichannel controlling of ferroelectric domains is still challenge, due to the lack knowledge on their bistability diverse physical stimuli. Herein, we have customized series perovskite ferroelectrics, (CnH2n+1NH3)2(CH3NH3)2Pb3Br10 (n = 2‐7), which Curie temperatures are modulated wide temperature range (ΔT 74 K) tailoring chain length organic...
Abstract Broadband photopyroelectric photodetectors (PDs) based on single crystal (SC) show potential in near‐infrared detection and imaging, attributed to their high crystalline properties, lack of grain boundaries, bias‐free. Nonetheless, the distinctive characteristic is attainable only with PDs crafted via polar crystallographic axis direction. This constraint directly results reported SC‐based being uniaxial, thus elevating intricacy expense manufacturing devices. Herein, a multi‐axis...

2D hybrid perovskites (HPs) have great potential for high-performance X-ray detection due to their strong radiation absorption and flexible structure. However, there remains a need explore avenues enhancing capabilities. Optimizing the performance through modification of structural properties presents promising strategy. Herein, we impact modifying organic spacer layer in two distinct layered HPs, namely, Ruddlesden–Popper (R-MPA)2PbBr4 (R-1, R-MPA = methylphenethylammonium) (R-MPA)EAPbBr4...
