High-quality CMOS compatible n-type SiGe parabolic quantum wells for intersubband photonics at 2.5-5 THz. [PDF]

open access: yesNanophotonics
Abstract A parabolic potential that confines charge carriers along the growth direction of quantum wells semiconductor systems is characterized by a single resonance frequency, associated to intersubband transitions. Motivated by fascinating quantum optics applications leveraging on this property, we use the technologically relevant SiGe material ...

Design of X-bar control chart based on Inverse Rayleigh Distribution under repetitive group sampling

open access: yesAin Shams Engineering Journal, 2021
The X¯ control chart is usually used in statistical quality control (SQC) to observe the change in procedure mean. In this paper, X¯ control chart for Inverse Rayleigh Distribution (IRD) is designed under repetitive group sampling at lower record values.
