Summary: Amorphous gallium oxide thin films were grown using plasma-enhanced atomic layer deposition. The films exhibited decreasing band gap energy and increased density as the temperature increased. The higher substrate temperature also resulted in increased surface roughness. Films grown at temperatures below 200 degrees C were amorphous, while the film grown at 250 degrees C showed slight crystallinity.

Summary: We present a microkinetic modeling framework that is based on first principle surface reaction thermodynamics to describe the process of silicon nitride thin film formation in plasma-enhanced atomic layer deposition. The results show that the relationship between silicon nitride growth per cycle (GPC) and quasi self-limiting behavior is consistent with experimental observations for both the dichlorosilane precursor dose and plasma nitridation time. GPC is ultimately limited to half a monolayer of Si3N4 structure. Importantly, we have observed a strong correlation between subsurface NH terminated Si group concentration and HF wet etch rate, which varies with substrate temperature.

Summary: Transition metal nitride thin films, such as TiN, are essential for memory and transistor devices as conducting electrodes. Recently, NbN thin films with a high work function (> 4.7 eV) have gained attention as replacements for TiN thin films in capacitor electrodes to reduce leakage currents. However, the conventional NbN ALD process resulted in high resistivity (> 500 mu omega center dot cm) due to residual Cl impurity (> 5%). This study proposes an alternative ALD surface reaction using H2S gas pulses to lower the Cl impurity concentration, leading to a significant decrease in resistivity (> 30%) of NbN thin films compared to the conventional NbN ALD process.

Summary: The study focuses on correlating basic plasma properties with morphological, structural and mechanical properties of thin films deposited by high power impulse magnetron sputtering. By studying the deposition and growth of titanium films at various discharge power densities, a transition from thermally-driven to ballistically-driven Ti atom mobility was revealed. Changes in micro-crystal orientation and nano hardness of the films were observed as discharge power density increased, alongside non-monotonic variations in surface roughness behavior.

Summary: This research investigates the effects of a starch-silver nanoparticle coating on the qualities of strawberries during postharvest life. The results show that the coated samples have lower weight loss, decay, and microbial counts compared to the uncoated samples. Additionally, the coating leads to higher total acidity and anthocyanin contents in strawberries. The washing process effectively removes silver particles, and the coating extends the shelf-life of strawberries.

The chemical composition of the films' top surface was investigated using XPS and FTIR measurements. Contact angle measurements were used to evaluate the hydrophilicity and wettability of the polymer films. After plasma deposition, a significant decrease in functional groups (OH and COOH) was observed, but sufficient functional groups remained for sensor applications. Broadband dielectric spectroscopy was used to analyze segmental mobility and conductivity, crucial for sensor applications.

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.
