MSc project: Probing doping and defects in semiconductor materials using high-harmonic generation

Work Activities

Doped semiconductor materials play a key role in electronic devices and integrated circuits. The continuous miniaturization of the active components on chips have further increased the necessity of highly controlled material quality. For high quality devices consistent quality control is required, which must be very sensitive, high-resolution, very fast and non-destructive. While the current standard for inspection is electron microscopy, optical techniques have the potential to greatly improve the detection speed while vastly reducing damaging capabilities. But to reap these benefits development is required to overcome limitations of resolution and sensitivity.

While doping and defects might greatly impact the electronic properties of a materials these changes are often not reflected in their optical properties. This resu...
