Summary: The attention in recent decades has been focused on the optoelectronic properties of indium and gallium chalcogenides, leading to advancements in fundamental and applied science. Group III-VI compounds have laminated structures that can be exfoliated to monolayers. Besides indium and gallium chalcogenides, there are other uncommon compounds in the family of group III-VI compounds, which have various crystal lattices, including layered structures. Aluminum chalcogenides show potential as anodes in batteries and semiconductors. Studies on thallium-based compounds are still exploring their semiconducting and thermoelectric properties. This review aims to summarize the significant features of these unusual materials and propose new studies to revive their potential in future technology.

Summary: Emerging 2D metallic layers exhibit diverse, tunable electronic properties and are more flexible than 3D crystals, with potential applications in electronic and optoelectronic fields. Theoretical calculations predict stable 2D allotropes of group 13 metals, with the preferred allotrope depending on substrate-induced strain. This suggests a new avenue for the discovery of thermodynamically stable 2D metallic layers.

Summary: Aluminium, gallium, and indium are group 13 metals with similar properties, and their toxic effects and protective mechanisms are poorly understood. This study identifies genes in yeast that play a role in resistance to these metals, providing a basis for further investigations in yeast, plants, and humans.

Summary: This study reports on the luminescence properties of novel coordination compounds based on trivalent group 3, 13 metals and the Q(CH) ligand. The coordination of metal ions leads to a significant increase in the luminescence quantum yields of the ligand. Molecular spectroscopy techniques reveal a correspondence between the energies of the ligand's excited states and the luminescence quantum yields to the metal ion's atomic numbers. The replacement of the central ion in the complexes affects the intersystem crossing rate and results in bright room-temperature phosphorescence.

Summary: This work presents a CMOS-compatible UVA photodetector based on a p-nickel-oxide/n-indium-gallium-zinc-oxide heterojunction for on-chip UV detection and imaging. The photodetector exhibits low dark current density, high peak quantum efficiency, fast photoresponse time, and excellent detectivity and linear photoresponsivity. It also shows great wavelength selectivity and UV/visible rejection ratio, making it promising for CMOS-compatible UVA detection and imaging.

Summary: In this study, the structural and photovoltaic properties of indium gallium phosphide (InxGa1-xP) alloys were carefully investigated. The results show that InxGa1-xP alloys can adopt zinc blende and wurtzite structures, and alloys with high indium concentrations have higher spectroscopic limited maximum efficiencies.

Summary: This study successfully soldered fine-grained 7034 aluminum alloys using Zn-5Al filler metals with liquid Ga as a protective coating. Applying the Ga coating only on the filler metal prevented the formation of detrimental intermetallic compounds, resulting in improved mechanical performance of the joints.

Summary: Nonlinear optical anionic group theory states that the anionic group mainly determines the NLO effect of materials. However, research shows that the AGa(2)Cl(7) (A = Ga+, In+) system exhibits significantly enhanced NLO polarizability due to the unique band structure and synergistic charge transfer effect between cations and anionic groups. Furthermore, monovalent Ga+/In+ cations induce enlarged birefringence, making them potential mid-infrared NLO materials.

Summary: The authors propose criteria for recess etching in order to fabricate T-gates for InGaAs high electron mobility transistors (HEMTs). By patterning additional rectangular pads on the source and drain metals during e-beam lithography, they are able to measure the drain-to-source resistance (R-ds) and current (I-ds). The ratio (& UGamma;) of R-ds and I-ds before and after etching can be used as a criterion to determine the optimal time to stop the etching process. By applying the proposed criteria, the authors have successfully fabricated InGaAs metamorphic HEMTs with excellent performance.

Summary: A novel n-InxGa1-xN/N-GaN homotype heterostructure IMPATT diode is proposed as an alternative to the GaN p-n IMPATT diode. The performance of the homotype heterojunction IMPATT improves as the In composition increases, with better frequency bandwidth and ability to withstand bias current density compared to p-n IMPATT.

Summary: This work reports a new type of Janus structures, Janus electrenes with different cation layers. By substituting one of the two zirconium cation layers in Zr2Cl2 with group I to III elements, nine Janus 2D materials have been generated, showing dramatically different electronic and magnetic properties. The results provide a new dimension of freedom to effectively tune the electronic and magnetic properties of electrenes, paving the way for novel applications.

Summary: This review discusses the coordination chemistry enabled by using univalent salts as starting materials, highlighting the significant impact of ligand quality on the reactivity of the lone pair in cations. Different ligands can either activate the lone pair for bond activation and oxidative addition reactions, or lead to the formation of highly charged cluster cations through aggregation.

Summary: This study focuses on fabricating amorphous gallium oxide through RF plasma sputtering and investigates the effects of metal doping and substrate preheating on its optical and electrical properties. The results show that aluminum doping significantly improves the mobility and conductivity of gallium oxide thin films, while europium doping does not have a noticeable impact.
