PhD defence: Shedding too much light on semiconductors
An investigation on laser-induced damage and ablation in semiconductors
PLEASE NOTE: If a candidate gives a layman's talk, the livestream will start fifteen minutes earlier.
My PhD thesis is about laser-induced damage in semiconductors. Laser light can be used to make permanent changes to a material. Such changes can be intentional, as well as unintentional. An example of an intentional change is for laser cutting. Unintentional changes are often called damage. With this research, we aim to figure out how and when such changes occur and which parameters influence this.
We mostly study materials that are relevant for the semiconductor industry. Pulse duration, wavelength and focus conditions all influence damage formation. These laser parameters are however not sufficient to predict laser induced damage. Material parameters like band gap and crystal structure of the studied material are also of importance.
Our research has led to new physical insights and we have performed innovative experiments. Additionally, our findings can be of use for the (Dutch) semiconductor industry.
