Type-II Red Phosphorus: Wavy Packing of Twisted Pentagonal Tubes
Jun-Yeong Yoon, Yangjin Lee, Dong-Gyu Kim +11
Elemental phosphorus exhibits fascinating structural varieties and versatile properties. The unique nature of phosphorus bonds can lead to the formation of extremely complex struct…
Band Gap Estimation of Multilayer 2D Semiconductor Channels Using Thin Graphite Contact
Sam Park, June Yeong Lim, Sanghyuck Yu +4
Band gap of monolayer and few layers in two dimensional (2D) semiconductors has usually been measured by optical probing such as photoluminescence (PL). However, if their exfoliate…
Complete determination of crystallographic orientation of ReX2 (X=S, Se) by polarized Raman spectroscopy
Yun Choi, Keunui Kim, Soo Yeon Lim +5
Polarized Raman spectroscopy on few-layer ReS2 and ReSe2 was carried out to determine the crystallographic orientations. Since monolayer ReX2 (X=S or Se) has a distorted trigonal s…
Antiferromagnetic ordering in van der Waals two-dimensional magnetic material MnPS3 probed by Raman spectroscopy
Kangwon Kim, Soo Yeon Lim, Jungcheol Kim +8
Magnetic ordering in the two-dimensional limit has been one of the most important issues in condensed matter physics for the past several decades. The recent discovery of new magne…
Magnetic excitations of the Cu quantum spin chain in SrCuPtO
J. C. Leiner, Joosung Oh, A. I. Kolesnikov +10
We report the magnetic excitation spectrum as measured by inelastic neutron scattering for a polycrystalline sample of SrCuPtO. Modeling the data by the 2+4 spinon contribu…
Anomalous polarization dependence of Raman scattering and crystallographic orientation of black phosphorus
Jungcheol Kim, Jae-Ung Lee, Jinhwan Lee +4
We investigated polarization dependence of the Raman modes in black phosphorus (BP) using five different excitation wavelengths. The crystallographic orientation was determined by…
Photocurrent generation at ABA/ABC lateral junction in tri-layer graphene photodetector
Minjung Kim, Seon-Myeong Choi, Ho Ang Yoon +6
Metal-graphene-metal photodetectors utilize photocurrent generated near the graphene/metal junctions and have many advantages including high speed and broad-band operation. Here, w…
