Polarization at the Nanoscale
Ke Yang, Zeyu Jiang, Duk-Hyun Choe +2
Modern polarization theory yields surface bound charge associated with spontaneous polarization of bulk. However, understanding polarization in nano systems also requires a proper…
Uncovering vacuum level in infinite solid by real-space potential-unfolding
Duk-Hyun Choe, Damien West, Shengbai Zhang
Although real materials are finite in size, electronic structure theory is built on the assumption of infinitely large solid, which led to a longstanding controversy: where is the…
Built-in potential and band alignment of matter
Duk-Hyun Choe, Damien West, Shengbai Zhang
The built-in potential is the interfacial potential difference due to electric dipole at the interface of two dissimilar materials. It is of central importance to the understanding…
Universal stability of two-dimensional traditional semiconductors
Michael C. Lucking, Weiyu Xie, Duk-Hyun Choe +3
Interest in two dimensional materials has exploded in recent years. Not only are they studied due to their novel electronic properties, such as the emergent Dirac Fermion in graphe…
