Molybdenum disulfide (MoS2) is a layered transition metal-sulfur compound semiconductor that shows promising prospects for applications in optoelectronics and integrated circuits because of its low preparation cost, good stability excellent physicochemical, biological mechanical properties. MoS2 with high quality, large size outstanding performance can be prepared via chemical vapor deposition (CVD). However, process complex, the area obtained difficult to control. Machine learning (ML), as powerful tool, has been widely applied materials science. Based on this, this paper, ML Gaussian regression model was constructed explore growth mechanism material CVD method. The parameters were evaluated by combining four indicators goodness fit (r2), mean squared error (MSE), Pearson correlation coefficient (p) p-value (p_val) Pearson’s coefficient. After comprehensive comparison, it found optimal when number iterations 15. Additionally, feature importance analysis conducted using established model. results showed carrier gas flow rate (Fr), molybdenum sulfur ratio (R) reaction temperature (T) had crucial impact materials. used predict synthesis under 185,900 experimental conditions simulation dataset so select range large-size disulfide. Furthermore, prediction verified through literature results. It relative between small. These findings provide an effective solution reduction time cost trial error.

2D transition metal dichalcogenide MoS2 monolayer quantum dots (MoS2-QD) and their doped boron (B@MoS2-QD), nitrogen (N@MoS2-QD), phosphorus (P@MoS2-QD), silicon (Si@MoS2-QD) surfaces have been theoretically investigated using density functional theory (DFT) computation to understand mechanistic sensing ability, such as conductivity, selectivity, sensitivity toward NH3 gas. The results from electronic properties showed that P@MoS2-QD had the lowest energy gap, which indicated an increase in electrical conductivity better adsorption behavior. By carrying out comparative studies m062-X, ωB97XD, B3LYP, PBE0 methods at 6-311G++(d,p) level of theory, most negative values were observed ωB97XD for surface, signifying preferred chemisorption surface detection. provided this study also indicate dopant is a promising material monitoring ammonia gas real world. We hope research work will provide informative knowledge experimental researchers realize potential dopants, specifically candidate sensors detect

The photoconductivity in monolayer MoS2 back-gate transistors is studied as a function of temperature and pressure. photocurrent increases linearly with the light intensity up to maximum responsivity ∼ 30 A W-1 air. Time-resolved measurements confirm that photoresponse dominated by photogating effect. device shows slow two time constants are attributed photobolometric effect desorption adsorbates, respectively. An enhancement observed above room below atmospheric pressure, when photoinduced adsorbates such O2 H2O molecules facilitated. Indeed, light-induced removal from surface enhances n-doping level current channel. Moreover, at lower pressures, reverse mechanism re-adsorption dark conditions suppressed results persistent photocurrent. study clarifies relaxation dynamics unveils key role optoelectronic properties other similar 2D materials.

We explore a phase engineering strategy to improve the electrochemical performance of transition metal sulfides (TMSs) in anode materials for lithium-ion batteries (LIBs). A one-pot hydrothermal approach has been employed synthesize MoS2 nanostructures. and MoO3 phases can be readily controlled by straightforward calcination (200-300) °C temperature range. An optimized 250 yields phase-engineered MoO3@MoS2 hybrid, while 200 300 produce single phases. When tested LIBs anode, hybrid outperforms pristine counterparts. With above 99% Coulombic efficiency (CE), retains its capacity 564 mAh g-1 after 100 cycles, maintains 278 at 700 mA current density. These favorable characteristics are attributed formation passivation surface layer on reactive interfaces between two phases, which facilitate Li-ion insertion/extraction, successively improving performance.
