Materials for applications in hostile environments, such as nuclear reactors or radioactive waste immobilization, require extremely high resistance to radiation damage, such as resistance to amorphization or volume swelling. Nanocrystalline materials have been reported to present exceptionally high radiation-tolerance to amorphization. In principle, grain boundaries that are prevalent in nanoma...

Direct laser writing of amorphous lines in crystalline silicon has the potential for becoming a flexible alternative to silicon-on-insulator technology photonic integrated circuits. Yet, maximum layer thickness achieved is 60 nm, which below requirements waveguiding at telecom wavelengths. Here, authors report on different strategies push beyond today's limit. To this end, irradiation with femt...
