Polarity Inversion in Polar-Nonpolar-Polar Heterostructures [PDF]
Physical Review Letters, 2001 We have observed an epilayer-thickness-dependent polarity inversion for the growth of CdTe on Sb(Bi)/CdTe(111)B. For films with Sb(Bi) thicknesses of less than 40 A (15 A), the CdTe layer shows a B (Te-terminated) face, but it switches to an A (Cd-terminated) face for thicker layers.

Multi-band spin-selective transmission and reflection in bi-layer T-shaped metamaterial
Results in Physics, 2023 The control of the spin angular momentum of light plays an irreplaceable role in modern photon applications. In this work, we proposed a chiral metamaterial based on a bi-layer T-shaped structure.

Non-Markovian speedup evolution of a center massive particle in two-dimensional environmental model
European Physical Journal C: Particles and Fields, 2023 A two-dimensional ray model is introduced to realize the non-Markovian speedup evolution of a center massive particle gravitationally coupled to a controllable environment (multilayer arrangement of the massive particles). By controlling the environment,

Polarization and Polar Codes [PDF]
Foundations and Trends® in Communications and Information Theory, 2012 This tutorial treats the fundamentals of polarization theory and polar coding. Arikan’s original results on binary source and channel polarization methods are studied. Error probability and complexity analyses are offered. The original results are generalized in several directions.
