Electric and Magnetic Tuning Between the Trivial and Topological Phases in InAs/GaSb Double Quantum Wells

Among the theoretically predicted two-dimensional topological insulators, InAs/GaSb double quantum wells (DQWs) have a unique double-layered structure with electron and hole gases separated in two layers, which enables tuning of the band alignment via electric and magnetic fields. However, the rich trivial-topological phase diagram has yet to be...

Gate-tunable high mobility remote-doped InSb/In1?xAlxSb quantum well

Gate-tunable high-mobility InSb/In1?xAlxSb quantum wells (QWs) grown on GaAs substrates are reported. The QW two-dimensional electron gas (2DEG) channel mobility in excess of 200?000?cm2/V?s is measured at T?=?1.8?K. In asymmetrically remote-doped samples with an HfO2 gate dielectric formed by atomic layer deposition, parallel conduction is...

Long-term regional simulation of tropical cyclones using a Generalized Stochastic Empirical Storm Model: A case study in the Western North Pacific

In coastal areas, Tropical Cyclones (TCs) are one of the greatest threats to humanity. Unfortunately, current risk reduction measures are not completely successful in lessening TC's consequences due to the remaining uncertainties in the estimates of key parameters, on which the designs of these measures rely. Because reliable observations of TCs...

General hurricane track and intensity model

This paper presents a new modeling technique to simulate the entire track of hurricane, starting with their initial points and ending with their landfall locations or final dissipations over the sea. The theoretical framework was first described in the literature by Vickery et al. (2000) and is extended in this study by introducing a new formula...

Investigation of long-term hurricane activity

This paper presents a new approach of applying numerical methods to model storm processes. A storm empirical track technique is utilized to simulate the full tracks of hurricanes, starting with their initial points over the sea and ending with their landfall locations or final dissipations. The theoretical framework was first described in the...
