Summary: In this study, we fabricated amorphous InSnO thin film transistors (TFTs) with high mobility and low thermal budget. The influence of thermal annealing on the properties of InSnO TFTs was investigated. The results show that annealing at 150 degrees C can significantly improve the carrier concentration and form a dense M-O-M network in the film. This research expands the application of amorphous oxide semiconductors in high mobility and flexible TFTs.

Summary: In this study, the corrosion mechanism of silica bricks used in hot stoves for over 10 years was analyzed. The results showed that silica bricks prepared using specific mineralizers exhibited good corrosion resistance, but were sensitive to certain substances due to their high amorphous content. The long-term usage resulted in delamination and changes in porosity of the bricks, caused by liquid migration and temperature changes.

Summary: At sub-3 nm nodes, the scaling of lateral devices faces challenges, while the development of vertical devices in the three-dimensional direction shows potential. However, current vertical devices encounter challenges in gate-channel self-alignment and precise gate length control. A recrystallization-based vertical C-shaped-channel nanosheet field effect transistor (RC-VCNFET) was proposed, with successful fabrication of the vertical nanosheet. Through physical characterization methods, the influencing factors of the crystal structure of the vertical nanosheet were analyzed. This lays the foundation for future fabrication of high-performance and low-cost RC-VCNFETs devices.

Summary: In this study, we investigated the effects of postdeposition annealing ambience on the nitrogen dioxide (NO2) gas sensing performance of a Si-based field-effect transistor (FET)-type gas sensor with indium-gallium-zinc oxide (IGZO) sensing material. We found that postannealing in a vacuum ambience resulted in a higher concentration of oxygen vacancy in the IGZO thin films, leading to a larger response to NO2 and excellent signal-to-noise ratio (SNR) and limit-of-detection performances.

Summary: The anharmonicity of thermal transport in amorphous solids, particularly in amorphous silica, has been investigated in this study. The results show the presence of significant anharmonicity in amorphous silica, including temperature-dependent linewidths and frequency shifts of the vibrational modes. By considering these anharmonic effects, the predicted temperature dependence of thermal conductivities agrees well with experimental observations. Moreover, the underlying mechanisms responsible for these effects have been revealed.

Summary: In this study, Fe83-xB10P4C2Cu1Vx (x = 0, 0.5, 1, 2) amorphous alloys were designed and prepared to enhance the soft magnetic properties. The effects of V addition on thermal stability, soft magnetic properties, and microstructure after annealing were investigated. The results showed that V effectively improved the thermal stability and the annealing process resulted in a composite structure that further enhanced the saturation magnetization and reduced the coercivity.

Summary: In this study, we demonstrate the use of an inorganic molecular insulating dielectric of antimony trioxide in amorphous Indium-Gallium-Zinc-Oxide thin film transistors. These transistors show enhanced field-effect mobility and bandlike transport, attributed to the dangling-bond-free interface nature of van der Waals bonded interaction. They also exhibit ideal onset speed with low subthreshold swing, indicating the suppression of interface defects and superior bias stress stability.

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.

Summary: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
