Phonon modes and Raman signatures of MnBi2nTe3n+1 (n=1,2,3,4) magnetic topological heterostructures
Yujin Cho, Jin Ho Kang, Liangbo Liang +8
An intrinsic antiferromagnetic topological insulator can be realized by intercalating Mn-Te bilayer chain in a topological insulator, . $\m…
Opto-electronic properties of alpha-In2Se3: single-layer to bulk
Yujin Cho, Sean M. Anderson, Bernardo S. Mendoza +8
In this work, we report linear and non-linear spectroscopic measurements of chemically-grown layered (from one to 37 quintuple layers) and bulk alpha-In2Se3 samples over a photon e…
General Theory for the Surface Second-Harmonic Generation Yield
Sean M. Anderson, Yujin Cho, Bernardo S. Mendoza
This manuscript is a revision of our previous work that develops the three layer model for the surface second-harmonic generation yield; here, we add the necessary algebra to deriv…
Bright visible light emission from graphene
Young Duck Kim, Hakseong Kim, Yujin Cho +18
Graphene and related two-dimensional materials are promising candidates for atomically thin, flexible, and transparent optoelectronics. In particular, the strong light-matter inter…
Out-of-plane Piezoelectricity and Ferroelectricity in Layered -In2Se3 Nano-flakes
Yu Zhou, Di Wu, Yihan Zhu +9
Piezoelectric and ferroelectric properties in the two dimensional (2D) limit are highly desired for nanoelectronic, electromechanical, and optoelectronic applications. Here we repo…
