Summary: Molybdenum disulfide (MoS2) is a promising semiconductor material, but its electrical performances in transistor structures are suppressed by interface trap density. Using MoS2 heterojunctions, high performance characteristics can be achieved, but varying the channel length leads to degradation of electrical performance.

Summary: By controlled stacking of graphene layers, the limitation of single-layer graphene as a material for light-emitting devices has been overcome, enabling twist-controlled resonant light emission. Experimental findings show light emission irrespective of the crystallographic alignment between the graphene electrodes, with a spectrally tunable resonant peak in the near-infrared range.

Summary: Molybdenum disulfides (MoS2) prepared through different methods exhibited varying levels of photo-induced antibacterial properties, with intercalation method showing the highest antibacterial effect due to its higher metal phase content, better light responsiveness, and smaller size. The main active substance in the photo-induced antibacterial process was found to be electrons, as determined through capture agent experiment and ESR test.

Summary: In addressing the high contact resistance in 2D devices, the use of thermal-evaporated ultrathin LiF between channel and source/drain metal has shown promising results in reducing RC values in MoS2 FETs. By utilizing the 4-bar FET method, lower RC values can be achieved, while transparent conducting oxide contact enables transparent MoS2 FETs to be realized.

Summary: Since the evaluation of CA 19-9 antigen level in human serum is important for the early diagnosis of various diseases, researchers developed a simple, rapid, and sensitive immunosensor using an electrolyte-gated field-effect transistor with MoS2 nanosheets. The immunosensor showed high selectivity and accurately detected trace amounts of the CA 19-9 antigen in real human serum samples. Its properties enable the early diagnosis of pancreatic cancer, increasing the chance of successful treatment.

Summary: Integration of schottky junction and defect engineering on adsorbent-semiconductors offers a promising strategy for photocatalytic reduction of U(VI). The BC-MoS2-x heterojunction exhibited high removal efficiency, cycle stability, and selective U(VI) removal in the presence of competing metal cations. The use of organic matter as a hole trapping agent to enhance U(VI) removal efficiency may pave the way for the development of rationally designed heterojunction photocatalysts.

Summary: Supercapacitors utilizing carbon nanotube electrodes can benefit from functionalization and graphenation processes to enhance charge densities and specific energy, as well as from the use of room-temperature ionic liquids to improve performance. Functionalization through atomic layer deposition offers pseudocapacitive energy storage mechanisms, while graphenation increases electrode surface area. These improvements in device performance were demonstrated through specific energy values of supercapacitors with different types of functionalizations.
