We study superconducting properties of NbN thin film samples with different thicknesses and an ultra-thin NbTiN meander nanowire sample.For the ultra-thin sampl
Based on the uniform,helical and spiral domain-wall magnetic configurations,the excited spin waves are studied with emphasis on the role of damping.We find that
Inhomogeneous electroluminescence(EL)of InGaN green LEDs grown on mesh-patterned Si(111)substrate had been investigated.Sample with n-AlGaN inserted between the
