Figure S5 from Hesam Khaksar et al. 2024 “A comparative nanotribological investigation on amorphous and polycrystalline forms of MoS2”: AFM image on the scratched area with the AFM (contact mode image) Fig. S5 shows a collection of images captured by the atomic force microscope, which displays scratches on two different materials. The first row shows scratches on amorphous material, while the second row shows scratches on polycrystalline material. Within each row, the force used to create the scratches was increased from 2 to 15 μN . The NANOSENSORS diamond coated DT-NCHR AFM probe was used to create the scratches and capture the images, allowing for a detailed examination of the surface features and material properties.

Molybdenum disulfide (MoS2) is commonly used as a dry lubricant due to its enhanced performance in the absence of oxygen and its elevated temperature stability,… Read More »A comparative nanotribological investigation on amorphous and polycrystalline forms of MoS2

Light-Induced Ferroelectric Modulation of p-n Homojunctions in Monolayer MoS2

Figure 3 from Mariola O Ramirez et al. 2024 “Light-Induced Ferroelectric Modulation of p-n Homojunctions in Monolayer MoS2”: c) Dark intensity-voltage (I–V) curves measured contacting the 1L-MoS2 by using two Pt-coated tips on a same single domain surface (blue) and both sides of a single domain wall (red). Schematics of the experimental configuration are shown in the right panels. Conductive NANOSENSORS™ AdvancedTEC™ ATEC-EFM tip-view AFM probes with a nominal stiffness of 2.8 N m−1 were used for the electrical characterization ensuring real tip visibility from above for a soft and accurate mechanical and electrical contact. To characterize the electrical properties of the system, the ATEC-EFM AFM probes were brought into direct contact with the MoS2 flakes please check the NANOSENSORS blogpost or the full article for the complete figure 3

In the last years, Transition Metal Dichalcogenides (TMDs) -based p-n junctions have been extensively studied and a variety of prototypes such as light-emitting diodes, photodetectors,… Read More »Light-Induced Ferroelectric Modulation of p-n Homojunctions in Monolayer MoS2
