Radiative electronic bound states in the continuum from defects in semiconductors
Seong Yun Hong, Liang Z. Tan, Ki Hoon Lee +2
Continuum-buried defect states in semiconductors are generally expected to be optically inactive due to their strong coupling to continuum bands. Here, we show that such defects ca…
Role of surface states and band modulations in ultrathin ruthenium interconnects
Gyungho Maeng, Subeen Lim, Mi Gyoung Lee +3
Mitigating the RC delay from transistor miniaturization is essential for next-generation devices, driving a focus on interconnect electrical performance. Current copper-based inter…
First-principles high-throughput screening of ruthenium compounds for advanced interconnects
Gyungho Maeng, Subeen Lim, Bonggeun Shong +1
As interconnect dimensions continue to shrink, the industry-standard copper faces a critical increase in resistivity, presenting a significant hurdle to overall device performance.…
Cobalt Binary Compounds for Advanced Interconnect Materials
Gyungho Maeng, Yeonghun Lee
The industrial standard copper (Cu) interconnects face a substantial resistivity increase at thinner linewidths, posing a well-known challenge to limit overall device performance.…
Validation of constant mean free path and relaxation time approximations for metal resistivity: explicit treatment of electron-phonon interactions
Subeen Lim, Yumi Kim, Gyungho Maeng +1
The figure of merit the product of resistivity and mean free path (MFP) evaluated from first-principles calculations, is widely adopted to screen promising interconnect meta…
