Flexible Hall sensor made of laser-scribed graphene [PDF]
npj Flexible Electronics, 2021 AbstractGraphene has shown considerable potential for sensing magnetic fields based on the Hall Effect, due to its high carrier mobility, low sheet carrier density, and low-temperature dependence. However, the cost of graphene in comparison to conventional materials has meant that its uptake in electronic manufacturing has been slow.

Two Concepts Changing Laser Scribing in Photovoltaics [PDF]
Laser Technik Journal, 2010 AbstractEven in established Photovoltaics (PV) production processes, such as laser structuring of thin‐film cells, there is always a need for further improvement. In a new scribing concept, several compact lasers replace high‐power lasers. This approach simplifies the system setup, reduces costs and is more flexible.

Thermal Stress Analysis on Laser Scribing of Glass
Journal of the Japan Society for Precision Engineering, Contributed Papers, 2004 In the laser scribing of glass a thermal stress is introduced into a glass substrate by means of a CO2 laser irradiation. The glass substrate is then rapidly cooled down by water jet immediately after the irradiation. For the purpose of theoretical clarification of the factors ruling the scribable condition and the crack depth, scribable conditions ...
