Key techniques for material characterisation

Electro-optical imaging

Electro-optical imaging combines imaging techniques with electro-optical properties to visualize material behavior under electric fields. This method is instrumental in real-world materials science applications, allowing researchers to observe how materials respond dynamically.

Photoluminescence

Photoluminescence involves the emission of light from a material after it absorbs photons. This technique helps in characterising semiconductors and organic materials by providing information related to band gaps and impurity levels, aiding in the assessment of material quality.

Electroluminescence

Electroluminescence occurs when a material emits light in response to an electric current. This property is especially advantageous for evaluating materials used in light-emitting devices, offering direct feedback on efficiency and performance.

Dark lock-in thermography

Dark lock-in thermography is a thermal imaging technique that reveals defects and inhomogeneities within materials. By applying a modulated heating input, researchers can identify subtle changes in temperature that correlate to material properties, making it critical for high-quality material assessment.

Deep-level transient spectroscopy

Deep-level transient spectroscopy (DLTS) is a powerful technique for characterising defects in semiconductors. It provides insights into the energy levels of deep traps within the bandgap, aiding in the optimisation of material properties for various applications.
