Magnetic Multilayer Edges in Bernal-Stacked Hexagonal Boron Nitride
Mehmet Dogan, Marvin L. Cohen
Single-layer -BN is known to have edges with unique magnetism, however, in the commonly fabricated multilayer --BN, edge relaxations occur that…
Observed Metallization of Hydrogen Interpreted as a Band Structure Effect
Mehmet Dogan, Sehoon Oh, Marvin L. Cohen
A recent experimental study of the metallization of hydrogen tracked the direct band gap and vibron frequency via infrared measurements up to ~425 GPa [P. Loubeyre et al., Nature 5…
High-Performance Atomically-Thin Room-Temperature NO2 Sensor
Amin Azizi, Mehmet Dogan, Hu Long +7
The development of room-temperature sensing devices for detecting small concentrations of molecular species is imperative for a wide range of low-power sensor applications. We demo…
Electron Beam-Induced Nanopores in Bernal-Stacked Hexagonal Boron Nitride
Mehmet Dogan, S. Matt Gilbert, Thang Pham +5
Controlling the size and shape of nanopores in two-dimensional materials is a key challenge in applications such as DNA sequencing, sieving, and quantum emission in artificial atom…
Causes of ferroelectricity in HfO-based thin films: An perspective
Mehmet Dogan, Nanbo Gong, Tso-Ping Ma +1
We present a comprehensive first principles study of doped hafnia in order to understand the formation of the ferroelectric orthorhombic [001] grains. Assuming that tetragonal grai…
Ferroelectric ZrO monolayers as buffer layers between SrTiO and Si
Mehmet Dogan, Sohrab Ismail-Beigi
A monolayer of ZrO has recently been grown on the Si(001) surface and shown to have ferroelectric properties, which signifies the realization of the lowest possible thickness…
