Experimental data characterizing inhomogeneous strain and piezoelectric effects in monolayer molybdenum disulfide (MoS2). The dataset was created by Edward Yu and last updated on October 15, 2025. Measurements were obtained using Kelvin probe force microscopy and electrostatic gating on length scales less than 100 nanometers.
Use Cases
- Modeling the relationship between strain and electrostatic potential based on nanoscale piezoelectric measurements.
- Analyzing the spatial distribution of the two-dimensional strain tensor from sub-100 nm scale data.
- Developing characterization methods for inhomogeneous strain that can be extended to other 2D materials.
- Isolating the contribution of strain from other electrostatic effects in atomically thin transition metal dichalcogenides.
Strengths
- Data enables measurement of all components of the two-dimensional strain tensor on sub-100 nm length scales.
- Methodology isolates strain contributions from other electrostatic effects, a noted challenge in the field.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
