Compared with bulk material-based sensors, functional sensors fabricated with nanomaterials have many advantages, such as high sensitivity, multifunctional integration, low power-dissipation, and low cost. Black phosphorus (BP) is a two-dimensional (2D) crystal material, which has a higher molecular adsorption energy, tunable direct band gap, high carrier mobility, ambipolar characteristics, and high current on/off ratio. In this paper, BP bulk was ground into powder, and then the powder was dispersed in dimethylformamide (DMF) to obtain two-dimensional BP nanosheets solution. Afterwards, the black phosphorus nanosheets and H2PtCl6 solution were mixed to obtain the Pt functionalized BP nanocomposite by one-step reduction method. Pt nanoparticles were dispersed on the surface of BP nanosheets with highly uniform size. The Pt functionalized BP nanocomposite exhibited a high response of 2.19 to 10 ppm NOx in a short period of 1.93 s at room temperature. The detection limit was as low as 30 ppb. The Pt functionalized BP nanocomposite will be useful for precise detection of NOx.

New Family

The two-dimensional(2D) materials are highly promising candidates to realise elegant and e cient transistor. In the present letter, we conjecture a novel co-planar metal-insulator-semiconductor(MIS) device(capacitor) completely based on lateral 2D materials architecture and perform numerical study of the capacitor with a particular emphasis on its di erences with the conventional 3D MIS electrostatics. The space-charge density features a long charge-tail extending into the bulk of the semiconductor as opposed to the rapid decay in 3D capacitor. Equivalently, total space-charge and semiconductor capacitance densities are atleast an order of magnitude more in 2D semiconductor. In contrast to the bulk capacitor, expansion of maximum depletion width in 2D semiconductor is observed with increasing doping concentration due to lower electrostatic screening. The heuristic approach of performance analysis(2D vs 3D) for digital-logic transistor suggest higher ON-OFF current ratio in the long-channel limit even without third dimension and considerable room to maximise the performance of short-channel transistor. The present results could potentially trigger the exploration of new family of co-planar at transistors that could play a signi significant role in the future low-power and/or high performance electronics.<br>

AbstractThe molybdenum disulfide (MoS2)-based photodetectors are facing two challenges: the insensitivity to polarized light and the low photoresponsivity. Herein, three-dimensional (3D) field-effect transistors (FETs) based on monolayer MoS2 were fabricated by applying a self–rolled-up technique. The unique microtubular structure makes 3D MoS2 FETs become polarization sensitive. Moreover, the microtubular structure not only offers a natural resonant microcavity to enhance the optical field inside but also increases the light-MoS2 interaction area, resulting in a higher photoresponsivity. Photoresponsivities as high as 23.8 and 2.9 A/W at 395 and 660 nm, respectively, and a comparable polarization ratio of 1.64 were obtained. The fabrication technique of the 3D MoS2 FET could be transferred to other two-dimensional materials, which is very promising for high-performance polarization-sensitive optical and optoelectronic applications.
