Abstract ：
The roll-off of quantum yield is a major challenge facing light-emitting diodes due to the inevitable predominant non-radiative recombination with temperature elevation. Here we report highly-efficient intrinsic electroluminescence (EL) from a biased highly-compensated ZnO:Ga (HC-GZO) microrod with a metal-semiconductor-metal (MSM) structure at high temperatures. The origin of the EL emission is the current-induced Joule heating activation of electric-thermal tunneling electrons and the following spontaneous radiation from multiple donor-acceptor-pair (DAP) recombination. The reduced oxygen vacancy (V-O) concentration via Ga doping promotes the electron-phonon coupling to lower the temperature threshold down to similar to 650 K, facilitating the stability and durability of MSM-EL devices. Meanwhile, an extra channel of radiative recombination is established by introducing Ga donor dopants, expanding the luminescence color space from orange (0.496, 0.445) to red (0.529, 0.408) by varying the V-O concentration in HC-GZO microrods. The present work motivates research on the mechanism and architectural design for novel electric-thermal tunneling induced efficient radiative emission devices at high temperatures using bandgap-engineered semiconductors.

Abstract ：
Here, we fabricated In2O3(ZnO)(m) (IZO) superlattice microplates with hexagon morphologies by the substrate-free optical vapor supersaturated precipitation. The IZO microplates possessed a superlattice structure with a large m number, i.e., m = 23, consisting of layered alternating stacks of octahedral InO2- as inversion boundaries and layered InZnmOm+1+ as a zig-zag modulated pattern. The Raman peak at 613 cm(-1) confirmed the superlattice of the IZO microplates. The broad asymmetric excitonic photoluminescence (PL) emission with the photon energy of 3.236 eV indicated the heavy doping of indium in the IZO, resulting a redshift of similar to 32 meV from the near-band-edge emission. The unusual negative thermal quenching of PL intensity was also observed. Moreover, the anisotropic electrical properties of the IZO superlattice microplates were manifested, for the first time, where the in-plane conductivity was two orders of magnitude higher than out-plane one. The present work provided new insight into the free-standing IZO superlattice microdevices for future optoelectronic applications.

Abstract ：
Here we report a novel ZnO microtubular homojunction photodiode (PD) fabricated by optical vapor supersaturated precipitation (OVSP) and sputtering methods. The acceptor-rich ZnO (A-ZnO) microtube grown by OVSP possesses a great UV-visible rejection ratio of similar to 3.77 and a high external quantum yield of 1.4 x 10(3)%. The formed A-ZnO/n-ZnO homojunction UV-PD realizes an ultrafast photoresponse down to 6 ms (three orders of magnitude faster) and boosts the sensitivity by 2.6-folds with respect to the bare A-ZnO microtube. It is beneficial for weak-signal UV detection down to the threshold of 0.4 mW/cm(2) under random excitation conditions, by which the detectivity up to 6.67 x 10(12) cmHz(1/2)/W is achieved. The ZnO microtubular homojunction paves a new way for design of high-performance wide-bandgap semiconductor UV-PDs, promoting their practical applications in future. (C) 2021 Elsevier B.V.

Abstract ：
Silver nanowires (Ag-NWs), which possess a high aspect ratio with superior electrical conductivity and transmittance, show great promise as flexible transparent electrodes (FTEs) for future electronics. Unfortunately, the fabrication of Ag-NW conductive networks with low conductivity and high transmittance is a major challenge due to the ohmic contact resistance between Ag-NWs. Here we report a facile method of fabricating high-performance Ag-NW electrodes on flexible substrates. A 532 nm nanosecond pulsed laser is employed to nano-weld the Ag-NW junctions through the energy confinement caused by localized surface plasmon resonance, reducing the sheet resistance and connecting the junctions with the substrate. Additionally, the thermal effect of the pulsed laser on organic substrates can be ignored due to the low energy input and high transparency of the substrate. The fabricated FTEs demonstrate a high transmittance (up to 85.9%) in the visible band, a low sheet resistance of 11.3 omega/sq, high flexibility and strong durability. The applications of FTEs to 2D materials and LEDs are also explored. The present work points toward a promising new method for fabricating high-performance FTEs for future wearable electronic and optoelectronic devices.
