The distinct behavior of specific heat of diluted magnetic semiconductor (Ga,Mn)As quantum wells

Autor: Tae Won Kang, Mingkai Li, Seung Joo Lee, Gukhyung Ihm, Hee Chang Jeon, S.A. Chizhik

Publikováno v: Current Applied Physics. 15:S26-S29

The phase transition and specific heat of carrier-induced diluted magnetic semiconductors (DMS) (Ga,Mn)As quantum well are investigated theoretically. With different concentration of magnetic ion and hole gas, there are three types of phase transitio

Gate-tunable valley-filter based on suspended graphene with double magnetic barrier structures

Autor: Nojoon Myoung, Gukhyung Ihm

Publikováno v: Current Applied Physics. 14:1455-1459

We theoretically investigate the effects of strain-induced pseudomagnetic fields on the transmission probability and the ballistic conductance for Dirac fermion transport in suspended graphene. We show that resonant tunneling through double magnetic

Fano resonance in electronic transport induced by the magnetic confinement in a graphene nanoribbon

Autor: Nojoon Myoung, Gukhyung Ihm, Kyungchul Seo

Publikováno v: Current Applied Physics. 13:1335-1338

Based on the Floquet scattering theory, a model of graphene-based electronic device is presented, in which electrical transport is controlled by adjusting Dirac fermions energy near resonance conditions. The presence of an oscillating field leads to

Demonstration of magnetic confinement in graphene with Fano-type resonances

Autor: Gukhyung Ihm, Nojoon Myoung, Kyungchul Seo

Publikováno v: Journal of the Korean Physical Society. 62:275-283

We demonstrate the magnetic confinement in graphene by investigating the Fano-type resonant features in the transmission spectra. The Fano-type resonance occurs due to the interference between extended states and magnetically-bound states as a result
