While layered materials are increasingly investigated for their potential in nanoelectronics,
their functionality and efficiency depend on charge injection into the materials via metallic …

While there has been growing interest in two-dimensional (2-D) crystals other than
graphene, evaluating their potential usefulness for electronic applications is still in its infancy …

We investigated the layer-number-dependent work function of MoS 2 nanoflakes by using
Kelvin probe force microscopy (KPFM) to measure the surface potential. The work functions …

Two-dimensional MoS 2-based materials are considered to be one of the most attractive
materials for next-generation nanoelectronics. The electrostaticproperties are important in …

Molybdenum disulfide (MoS 2) is currently under intensive study because of its exceptional
optical and electrical properties in few-layer form. However, how charge transport …

We report the interlayer screening effects of ultrathin MoS 2 nanoflakes with different
thicknesses by measuring their surface potential using Kelvin probe microscope. Surface …

Thinning out MoS 2 crystals to atomically thin layers results in the transition from an indirect
