A Novel Analytic Approach to Model Line Edge Roughness using Stochastic Exposure Distribution in Electron-beam Lithography
Rui Guo, Soo-Young Lee
The line edge roughness (LER) becomes a issue of e-beam lithography when feature size is reduced into nanometers. Therefore, minimizing the LER is a important method to increase th…
Multi-Valued Logic Gates based on Ballistic Transport in Quantum Point Contacts
M. Seo, C. Hong, S. -Y. Lee +5
Multi-valued logic gates, which can handle quaternary numbers as inputs, are developed by exploiting the ballistic transport properties of quantum point contacts in series. The pri…
Resonant tunnelling and quenching of tunnel splitting in Wess-Zumino nanospin systems
Soo-Young Lee, Sahng-Kyoon Yoo
We investigate the energy spectrum of the biaxial spin systems with magnetic field along the hard anisotropy axis by using the complex periodic orbit theory. All important features…
Geometrical phase effects in biaxial nanomagentic particles
Sahng-Kyoon Yoo, Soo-Young Lee
The oscillation of tunnel splitting are obtained by geometrical analysis of the topological Wess-Zumino phase on the basis of tunneling paths in biaxial nanomagnetic particles with…
Oscillation of the tunnel splitting in nanospin systems within the particle mapping formalism
Sahng-Kyoon Yoo, Soo-Young Lee, Dal-Ho Yoon +1
The oscillation of tunnel splitting in the biaxial spin system within magnetic field along the anisotropy axis is analyzed within the particle mapping approach, rather than in the…
