Transport techniques are experimental methods used to measure and analyze the movement of charge carriers, mass, or energy through a medium under applied gradients or fields. In condensed matter and materials science, they encompass electrical transport measurements such as four-probe resistivity, Hall effect, magnetoresistance, and thermoelectric characterization, which quantify conductivity, carrier density, mobility, and scattering mechanisms. These techniques often involve controlling temperature, magnetic field, and sample geometry to resolve intrinsic transport coefficients and distinguish bulk from interfacial or defect-dominated contributions, thereby enabling rigorous evaluation of electronic structure, disorder, and phase transitions in materials.

If one side of a conducting or semiconducting material is heated while the other remains cool, charge carriers move from the hot side to the cold side, generating an electrical voltage known as thermopower.
Semiconducting transition metal dichalcogenides (TMDs) are a class of layered materials exhibiting unique optoelectronic properties that could be leveraged to develop transistors, sensors and other nanoelectronics. Despite ...
