Electrical Transport Measurements
Electrical transport measurements are a fundamental technique in condensed matter physics that involve studying the way electric currents flow through materials. By applying a voltage across a sample and measuring the resulting current, researchers can extract valuable information about the material's electronic properties, such as its conductivity, resistivity, mobility, and carrier concentration. These measurements provide insights into the material's band structure, charge carrier behavior, and interactions, offering a deeper understanding of its electronic properties and potential applications. Electrical transport measurements are crucial for characterising and designing electronic devices like transistors, semiconductors, and superconductors, and they play a pivotal role in advancing fields such as solid-state physics, materials science, and electronics research.
