It really is the specific wavelength. Higher or lower is easier. But euv has tricky properties which make it feasible for Lithography (although just barely it you have a look at the optics) but hard to produce with high intensities.
- YetAnotherNick 8mo agoAny source to this? I am hearing this for the first time.
- s0rce 8mo agoITs easy to make X-rays, you just hit a metal target with electrons: https://en.wikipedia.org/wiki/X-ray_tube https://en.wikipedia.org/wiki/X-ray_tube
- YetAnotherNick 8mo agoYou can hit metal the same way for EUV.
- s0rce 8mo agoI assume this doesn't work well otherwise everyone would be doing it.
- on_the_train 8mo agoNo you can't, or rather you only get a tiny amount in the correct wavelengths
- formerly_proven 8mo agoSpecifically, what makes x-rays easy to generate are these: https://en.wikipedia.org/wiki/Characteristic_X-ray https://en.wikipedia.org/wiki/Characteristic_X-ray In essence, smashing electrons into atoms allows you to ionize the inner shell of an atom and when an electron drops down from an outer shell, the excess energy is shed as high-energy photons. This constrains the energy range of X-ray tubes ("smash electron into metal") to wavelengths well below 13.5nm. (These emission lines are also what is being used in x-ray spectroscopy to identify elements)
- s0rce 8mo agoYou can also generate broad spectrum bremsstrahlung radiation easily, this is widely used for medical X-rays.
