In the recent past, extensive studies were performed on nanoscale materials. In particular, bismuth nanowires attracted large interest because of their extraordinary properties and possible application in thermoelectric devices. Regarding future implementations, the maximal current density jmax nanowires are able to carry is an important aspect. High current densities can cause voids in the wir...

All Semrock filters are proven to be exceptionally durable and environmentally reliable, even in hot and high-humidity conditions, and are capable of withstanding high optical intensities. Semrock filters either have laser damage threshold (LDT) specifications, or, depending on the application, have been tested with intense broadband sources for extended periods of time with no noticeable degra...
