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: The application of (In, Al, Ga)N materials in photovoltaic devices has attracted much attention. However, to deposit high-quality GaN material as a foundation is essential. Plasma-enhanced atomic layer deposition (PEALD) combines the advantages of ALD process with plasma utilization and has been used to deposit thin films with various requirements. In this study, NH3-containing plasma was used to eliminate the residual oxygen during the growth of GaN films, which significantly improved the quality of the films. The plasma power controlled NH2, NH, and H radicals showed strong influence on the oxygen content, growth rate, crystallinity, and surface roughness of the GaN films.

Summary: In this study, ultra-thin aluminum nitride (AlN) films with a thickness of 5 nm were successfully prepared using plasma enhanced atomic layer deposition (PE-ALD) on gallium nitride (GaN) substrates, and their structural, chemical, and electrical properties were investigated. The formation of a sharp epitaxial interface between AlN and GaN resulted in the creation of a two-dimensional electron gas (2DEG), with excellent current transport properties demonstrated through various analysis techniques. The electron transport through the AlN film followed the Fowler-Nordheim tunneling mechanism, with an average barrier height in good agreement with the expected AlN/GaN conduction band offset.

Summary: In this study, high-performance Ga2O3 SBPDs with a 20 nm ultra-thin film were fabricated. The SBPDs exhibited low dark current (0.76 pA), high photo-dark current ratio (106), high responsivity (6.18 A/W), and ultra-fast decay time (45 ms) after annealing in nitrogen ambient at 900 degrees C. The Ga2O3 films annealed in nitrogen showed a more pronounced amorphous-to-polycrystalline transition and lower recrystallization and oxygen vacancy concentration after oxygen annealing. This work provides a desirable strategy for developing high-performance SBPDs.

Summary: Interest in atomic layer deposition (ALD) processes on polymer substrates is driven by the growth of organic electronics and polymer-based nanodevices. This study investigates the initial growth and interface formation during plasma-enhanced ALD (PE-ALD) of ZnO on poly ethylene glycol dimethylacrylate (pEGDMA) and poly 2-hydroxyethyl methacrylate (pHEMA) thin films. The findings reveal that PE-ALD growth on polymers is influenced by both polymer etching and ZnO nucleation and growth, providing valuable insights for the development of new processes and applications.

Summary: Yttria-stabilized zirconia (YSZ) doped with yttrium has been widely used in electronic and energy devices. In this study, we report the thermal conductivity of YSZ thin films with varying Y2O3 content deposited by plasma-enhanced atomic layer deposition (PEALD). The results show that the thermal conductivity decreases with increasing Y2O3 doping concentration, mainly due to increased phonon scattering by oxygen vacancies. Our PEALD YSZ films have higher thermal conductivities compared to previously reported films, possibly due to their relatively larger grain sizes.

Summary: This study presents a flexible strategy for the deposition of phase-controlled bimetallic nanoparticles (BMNPs) by vapor-phase titration of a secondary metal to a pre-deposited monometallic nanoparticle (NP) host. The method allows for precise control over the structure and composition of the BMNPs through substrate temperature control and the addition of hydrogen gas. The approach provides a single-step, selective vapor-phase conversion of the monometallic NPs into phase-controlled BMNPs with potential applications in catalysis.

Summary: This work reports on the atomic layer deposition process combining lithium hexamethyl disilazide (LiHMDS) and trimethylphosphate (TMP), and studies the impact of adding a trimethylaluminum (TMA) pulse to this process. The interaction between TMA and TMP plays a key role in this process, and the addition of TMA leads to higher growth and structural changes in the deposited layer. The amorphous mix of Li4P2O7 and Li3PO4 in the films grown with TMA improves the conductive properties of the material, making it potentially useful for modifying electrode-electrolyte interfaces in lithium-ion batteries.

The photonic circuits, designed at a wavelength of 360 nm, enable super-resolved imaging with UV light and do not require modification of the traditional imaging protocol. As a biological application, the UV photonic chips revealed features that cannot be resolved using standard wide-field microscopy.

Summary: This study presents a low-temperature atomic layer deposition (ALD) process for ruthenium dioxide (RuO2) using a combination of inorganic precursor and alcohols. The process allows for linear growth with controlled growth rate. Various analyses confirm the composition and structure of the deposited material, revealing both amorphous and crystalline phases. The films also show conductivity and can be crystallized through thermal annealing. The proposed ALD reaction mechanism involves the reduction and reoxidation of the RuO2 surface by alcohols and RuO4, respectively.

Summary: This work investigates the properties and robustness of post metallization annealed Al2O3 atomic layers on n-type GaN in terms of chemical, physical, and electrical aspects. The study demonstrates a gate-first process flow with subsequent ohmic contact formation at temperatures up to 600 degrees C using planar metal insulator capacitors. The results show no new bonds or crystallization in the Al2O3 layer due to annealing, but degradation is observed at 600 degrees C. The annealing temperature affects the oxide depletion and deep depletion capacitances, resulting in a reduction of the flat band voltage to zero.
