Effects of Ni irradiation on electron–phonon coupling and flux pinning in MgB2 film via Raman spectroscopy
Effects of Ni-ion irradiation on the structural and flux-pinning properties of MgB2 films were investigated with particular importance on the role of Raman spectroscopy. MgB2 films (∼400 nm thick) wer...
Dark-mode lightning-rod effect in meta-structures
A dark-mode lightning-rod effect has been studied using the meta-structures. In the meta-structure, the metal wires with the tapered terminals are employed as the dark resonators. Due to near-field co...
Multi-step trap-assisted tunneling in Al-doped HfO2 used in advanced 2.5D metal–insulator–metal capacitors
Leakage currents through back-end dielectric layers critically affect the performance and reliability of modern electronic devices. In particular, high-κ dielectrics, such as HfO2, used in backend-int...
