Towards a new generation of polymer nanocomposites based on inorganic nanotubes

A significant enhancement of the thermal stability of the nanocomposites and a nucleating effect of the inorganic nanotubes comparable to carbon nanotubes has been observed. The excellent dynamic mechanical data demonstrates the high-performance of these novel iPP/IN-MoS2 nanocomposites for industrial applications.

Transistors with chemically synthesized layered semiconductor WS[sub]2 exhibiting 10[sup]5 room temperature modulation and ambipolar behavior

We collaborated in construction of FET based on 2D WS2 crystals. Two-dimensional Schottky FET demonstrated ambipolar behavior and a high (~105x) on/off ratio at room temperature with current saturation. irradiation with visible light strongly increased drain current due to formation of exitons.

Optical properties of exfoliated MoS[sub]2 coaxial nanotubes - analogues of graphene

Optical investigation of exfoliated MoS2 nanotubes has shown low degree of restacking, quantum confinement as a size effect and a strong blue shift of exitons. The MoS2 single layers represent inorganic graphene analogy.

Comparative study of chemically synthesized and exfoliated multilayer MoS[sub]2 field-effect transistors

We have collaborated in construction of the first field effect transistor based on thin flakes produced by chemical transport reaction and compared results with FET based on exfoliated MoS2. While elektronic and structural properties are similar, the transistor characteristics are almost identical.

Friction on a single MoS2 nanotube

For the first time we have measured friction on a single MoS2 nanotube and nano-onion. We confirmed predictions of rolling mechanisms at low loads. We evidenced dependance of friction on interaction strength with the substrate and explained the effect with dissipation of energy.
