Effects of radiodarkening on the light transmission properties of ytterbium-doped optical fibers

Çamiçi, Hüseyin Can (Bilkent University, 2021-03)

Optical ﬁbers have been acting in a very crucial role in telecommunication and non-telecom industries like medicine, machining, sensing as well as in lasers and ampliﬁers when they are doped with rare earth ions for their ...
Electrical conduction and dielectric relaxation properties of AlN thin films grown by hollow-cathode plasma-assisted atomic layer deposition

Altuntas, H.; Bayrak, T.; Kizir, S.; Haider, A.; Bıyıklı, Necmi (Institute of Physics Publishing, 2016)

In this study, aluminum nitride (AlN) thin films were deposited at 200 ï¿½C, on p-type silicon substrates utilizing a capacitively coupled hollow-cathode plasma source integrated atomic layer deposition (ALD) reactor. The ...
