Strontium transition frequency measurements assisted by a photonic grating chip
Jaewhan Lee, Hyun Gyung Lee, Won-Kyu Lee +15
We measure the absolute frequency of the transition in strontium using two methods: fluorescence spectroscopy of a thermal atomic beam sourc…
Contact holes in vertical electrode structures analyzed by voltage contrast-SEM and conducting AFM
Minsun Gu, Moon Seop Hyun, Moonsup Han +2
Soaring demands of multi-stacked memory devices request urgent development of backside contact electrode technologies, such as high aspect ratio etching, metallization, and inspect…
Introduction of Sr into Bi2Se3 thin films by molecular beam epitaxy
L. Riney, C. Bunker, S. -K. Bac +7
SrxBi2Se3 is a candidate topological superconductor but its superconductivity requires the intercalation of Sr by into the van-der-Waals gaps of Bi2Se3. We report the synthesis of…
Thickness-Controlled Black Phosphorus Tunnel Field-Effect Transistor for Low Power Switches
Seungho Kim, Gyuho Myeong, Wongil Shin +7
The continuous down-scaling of transistors has been the key to the successful development of current information technology. However, with Moore's law reaching its limits, the deve…
Structural, magnetic, and electrical properties of collinear antiferromagnetic heteroepitaxy cubic MnGa thin films
Hyun-Woo Bang, Woosuk Yoo, Chungman Kim +5
Although a cubic phase of MnGa with an antiferromagnetic order has been theoretically predicted, it has not been experimentally verified in a bulk or film form. Here, we report…
Quantum electronic transport of topological surface states in beta-Ag2Se nanowire
Jihwan Kim, Ahreum Hwang, Sang-Hoon Lee +8
Single-crystalline β-Ag2Se nanostructures, a new class of 3D topological insulators (TIs), were synthesized using the chemical vapor transport method. The topological surface state…
Quantum interference effects in chemical vapor deposited graphene
Nam-Hee Kim, Yun-Sok Shin, Serin Park +5
We report several quantum interference effects in graphene grown by chemical vapor deposition. A crossover between weak localization and weak antilocalization effects is observed w…
Quantum electrical transport properties of topological insulator Bi2Te3 nanowires
Hong-Seok Kim, Ho Sun Shin, Joon Sung Lee +3
We investigate the quantum transport properties of surface electrons on a topological insulator Bi2Te3 nanowire in a magnetotransport study. Although the nanowires are synthesized…
Ballistic transport of graphene pnp junctions with embedded local gates
Seung-Geol Nam, Dong-Keun Ki, Jong Wan Park +3
We fabricated graphene pnp devices, by embedding pre-defined local gates in an oxidized surface layer of a silicon substrate. With neither dielectric-material deposition nor electr…
