Article Synopsis
- The study used time-dependent density functional theory to analyze how MoS2 (a semiconductor material) reacts to laser pulses, focusing on factors like laser wavelength, intensity, and polarization.
- Findings revealed that the way MoS2 absorbs energy changes at different laser intensities, particularly distinguishing between infrared (IR) and ultraviolet (UV) lasers.
- The research has important implications for improving MoS2 photodetectors, especially in terms of their performance and durability when exposed to powerful short-wavelength lasers.

The development of materials with high ambipolar mobility is pivotal for advancing multifunctional applications, yet such materials remain scarce. Presently, cubic boron arsenide (BAs) stands out as the premier ambipolar material, demonstrating an ambipolar mobility of ∼1600 cm V s at room temperature [ 2022, 377, 433 and 2022, 377, 437]. Herein, we illustrate that semiconducting AlBC, featuring a nonclathrate B-C framework in which a C atom bonds to the vertices of four distorted hexagonal antiprism B units via quasi-sp hybridization, is predicted to possess ambipolar carrier transport behavior.

The discovery of ferroelectricity in hafnia based thin films has catalyzed significant research focused on understanding the ferroelectric property origins and means to increase stability of the ferroelectric phase. Prior studies have revealed that biaxial tensile stress via an electrode "capping effect" is a suspected ferroelectric phase stabilization mechanism. This effect is commonly reported to stem from a coefficient of thermal expansion (CTE) incongruency between the hafnia and top electrode.

Besides the symmetry breaking of Janus transition metal dichalcogenides (TMDs), Janus-based Diluted Magnetic Semiconductors (DMS) are attractive to study considering the local symmetry of transition metal (TM) dopant/adatom. This study conducts a first-principles calculation of magnetic properties in TM (V, Cr, Mn, Fe, and Co) -- doped and adsorbed Janus WSSe. Our results reveal that TM's atomic/ionic size impacts d-p-d orbital overlap, affecting bond length/angle and defect state positions.

Copper oxide high-temperature superconductors, such as BiSrCaCuO (Bi2212), have garnered extensive research interest due to their high critical temperatures (T) surpassing the Bardeen-Cooper-Schrieffer (BCS) limit. The two-dimensional CuO₂ plane is widely regarded as the most crucial element of high-T cuprate superconductors. The anisotropy of this CuO₂ layer remains a topic of ongoing interest.
