Electronic band structure of InAs/InAsSb type-II superlattice for HOT LWIR detectors

open access: yesResults in Physics, 2018
The InAs/InAs1−xSbx type-II superlattices (T2SLs) grown on GaSb buffer layer and GaAs substrates have recently been applied for detectors for long wavelength infrared (LWIR) range and high operating temperature (HOT) conditions.

The Dependence of InAs/InAsSb Superlattice Detectors’ Spectral Response on Molecular Beam Epitaxy Growth Temperature

open access: yesApplied Sciences, 2022
In this paper, we report on the influence of molecular beam epitaxial (MBE) growth temperature on the spectral response of the long-wavelength infrared radiation (LWIR), three-stage thermoelectrically (TE) cooled (T = 210, 230 K) InAs/InAsSb type-II ...

Super-lattice, rhombus, square, and hexagonal standing waves in magnetically driven ferrofluid surface

open access: yes, 2000

Superlattice-induced ferroelectricity in charge-ordered La$_{1/3}$Sr$_{2/3}$FeO$_{3}$ [PDF]

open access: yes, 2019
Charge-order-driven ferroelectrics are an emerging class of functional materials, distinct from conventional ferroelectrics, where electron-dominated switching can occur at high frequency.

Modeling Energy Bands in Type II Superlattices [PDF]

open access: yesCrystals, 2019
We present a rigorous model for the overall band structure calculation using the perturbative k · p approach for arbitrary layered cubic zincblende semiconductor nanostructures. This approach, first pioneered by Kohn and Luttinger, is faster than atomistic ab initio approaches and provides sufficiently accurate information for optoelectronic ...

Magnetic and Structural Response Tuned by Coexisting Mn Concentration‐Dependent Phases in MnBi2Te4 Thin Film Grown on GaAs(001) by Molecular Beam Epitaxy

open access: yesAdvanced Functional Materials, EarlyView.
The study explores structural and magnetic properties of one of the most recent topological quantum materials (MnBi2Te4). The Mn‐poor structure leads to stacking faults (quintuple layer ‐ QL of Bi2Te3 formation instead of a septuple layer ‐ SL of MnBi2Te4), resulting in a coexistence between weak antiferromagnetism and ferromagnetism.

InAs/GaSb Type-II Superlattice Detectors

open access: yesAdvances in Electronics, 2014
InAs/(In,Ga)Sb type-II strained layer superlattices (T2SLs) have made significant progress since they were first proposed as an infrared (IR) sensing material more than three decades ago. Numerous theoretically predicted advantages that T2SL offers over present-day detection technologies, heterojunction engineering capabilities, and technological ...

Domain‐Wall‐Free Sliding Ferroelectricity in Fully Commensurate 3R Transition Metal Dichalcogenide Bilayers

open access: yesAdvanced Functional Materials, EarlyView.
It is reported that the ferroelectric switching behavior of rhombohedral (3R) phase transition metal dichalcogenide (TMD) bilayers strongly depends on their domain structures. Single‐domain TMDs (SD‐TMDs) with domain‐wall‐free structures exhibit robust and stable polarization switching, whereas poly‐domain TMDs (PD‐TMDs) with randomly distributed ...
