Summary: In this study, we achieved an ohmic contact with a flat interface using low-temperature annealing. Our results showed that annealing at 200 degrees C reduced the Schottky barrier height and had minimal effect on surface roughness. By utilizing the low-temperature process, we obtained contact resistivity comparable to high-temperature annealing on heavily doped substrates.

Summary: This paper investigates the electrical and structural properties of Cu/Ti/Al ohmic contacts to p-type 4H-SiC with different annealing temperatures and Cu layer thicknesses. The results show that the Cu/Ti/Al contact forms ohmic contact with a contact resistivity of 1.0×10-4 Ω·cm2 after annealing at 800 degrees C. The surface roughness and number of pits on the sample surface increase with the increase of annealing temperature.

Summary: The performance of SiC MOSFETs is limited by defects at the SiC/SiO2 interface, with selective oxidation of Si in SiC due to the high heat of formation of SiO2 leaving carbon clusters. Only carbon clusters have a low enough formation energy to explain the mobility loss observed, according to experimental evidence.

Summary: Achieving effective Ohmic contact between SiC and metal electrodes remains a challenge due to the high Schottky barrier. One promising approach is to introduce a high-work-function interfacial layer. However, the interaction mechanisms between the interfacial layer and the SiC substrate have been rarely studied. In this work, layers of high-work-function MoO3 and Pt were grown on the SiC surface, and the evolutions of the system during annealing under different environments were studied. The results provide a detailed understanding of the Pt/MoO3 interface and its response to various conditions.

Summary: This study investigates the impact of SiO2 layers on 4H-SiC, with findings indicating that NO annealing can enhance channel mobility and reduce the total amount of interface states. Electron energy loss spectroscopy reveals that the reduction of traps in the NO annealed sample is attributed to lower amounts of sub-stoichiometric silicon oxide and carbon-related defects at the interface.

Summary: All-optical switches have attracted significant attention due to their ultrafast speed compared to electric switches. The exceptional optical properties and strong interaction of two-dimensional (2D) material MXene indicate its great potential in next-generation all-optical switching. In this study, we propose using Au/MXene for all-optical switching with a switching full width at half maximum (FWHM) operating at 290 fs. Compared to pure MXene, the Au/MXene exhibits outstanding performances, such as broadband differential transmission and strong enhancement in near-infrared on/off ratio, due to local surface plasmon resonance (LSPR). Importantly, this research demonstrates a red shift of approximately 34 nm in the ultrafast all-optical switching of Au/MXene compared to MXene, validating its all-optical properties and paving the way for optical interconnection and optical switching.

Summary: The water pollution caused by pharmaceutical products, such as the antibiotic ceftriaxone (CEF), has become a major concern for the sustainability of ecosystems and human health. Even at low concentrations, CEF has lethal effects. TiO2 is considered an effective nanoparticles for CEF removal, but its performance is hindered by a wider energy gap and rapid recombination of charge carriers. This study synthesized activated carbon based TiO2 (ACT-X) nanocomposites to improve TiO2's intrinsic properties and enhance its adsorption-photocatalytic performance for CEF removal.

Summary: Since the end of 2019, a highly contagious disease called COVID-19, caused by SARS-CoV-2, has claimed numerous lives worldwide. The latest variant of concern is omicron, and BA.5 is becoming the dominant subtype, replacing the BA.2 variant. These subtypes have an L452R mutation, which increases their transmissibility among vaccinated individuals. Current methods for identifying SARS-CoV-2 variants rely on time-consuming and costly PCR-based gene sequencing. In this study, researchers developed a rapid and ultrasensitive electrochemical biosensor using MXene-AuNP electrodes and the CRISPR/Cas13a system to detect the L452R mutation in RNA samples, enabling early diagnosis and distinguishing omicron BA.5 and BA.2 variants.

Summary: In this study, we use transient absorption spectroscopy combined with density functional theory calculations to demonstrate ultrafast exciton absorption modulation by tailoring the size of a transition-metal dichalcogenide alloy Mo0.64W0.36S2 nanosheet. By increasing the size of the nanosheet from 9 +/- 5 to 190 +/- 121 nm, the peak positions of the A and B excitons shift from 666 to 675 nm and from 626 to 638 nm, respectively. Additionally, the decay lifetimes of the A excitons slow down from 1.16 to 1.84 ps with increasing nanosheet size. These results show that exciton diffusion and decay properties can be modulated by adjusting the components and structure, which is beneficial for the optimal design and optimization of optoelectronic devices.

Summary: Recently, germanium (Ge) has been regarded as a two-dimensional (2D) material saturable absorber (SA) due to its excellent nonlinear saturable absorption properties. However, research on Ge SA Er-doped fiber lasers is still limited. In this study, bound state solitons were successfully demonstrated in a Ge SA Er-doped fiber laser, which has not been achieved in previous works. Three types of bound state solitons with a fundamental frequency of 9.77 MHz were investigated, indicating that Ge has exceptional nonlinear optical characteristics to promote the development of bound state solitons.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
