	abstract = {A layered two-dimensional semiconductor, indium selenide (InSe), has gained popularity due to its thickness-dependent electronic properties and potential applications in nanoelectronics and optoelectronics. In this study, we conduct a first-principles investigation on bulk-, monolayer (ML-), and bilayer (BL-) InSe. Band structures and density of states were calculated for the different layer configurations. In all cases, InSe exhibited semiconducting characteristics. Among the three structures, ML-InSe has the largest band gap, followed by BL-InSe and bulk-InSe. We also observe that ML- and BL-InSe have indirect band gaps, while bulk-InSe has a direct band gap at the Γ point. These results suggest that the electronic properties of InSe can be tuned by controlling the number of layers, making it a promising candidate for electronic and optoelectronic applications.},

	abstract = {A family of two-dimensional transition metal carbides and nitrides, collectively known as MXenes, has garnered significant interest since their discovery in 2011 due to their unique properties and versatile applications. Here, we conduct a theoretical study on Hf$_{3}$N$_{2}$T$_{2}$ with various surface terminations, T$_{2}$, T = O, F, and OH. Band structures, density of states, and projected density of states for the various surface terminations were calculated. In all cases, the MXene monolayers exhibited metallic characteristics. Among all the tested surface functionalizations, Hf$_{3}$N$_{2}$O$_{2}$ showed the highest electronic density of states close to the Fermi energy level, suggesting that {\textendash}O terminated Hf$_{3}$N$_{2}$ is the most promising candidate for electronic applications requiring high electrical conductivity.},
