Null controllability of semilinear degenerate parabolic equations in bounded domains

Electronic Journal of Differential Equations, 2006
In this paper we study controllability properties for semilinear degenerate parabolic equations with nonlinearities involving the first derivative in a bounded domain of R. Due to degeneracy, classical null controllability results do not hold in general.

Extremely High Electron Mobility in GeSn Epitaxial Films by Chemical Vapor Deposition

Advanced Electronic Materials, EarlyView.
Transport properties in n‐GeSn films are investigated. By applying tensile stress or increasing the Sn fraction, electron mobility is significantly enhanced since more electrons populate the Γ‐valley, where the electron effective mass is small. A remarkably high electron Hall mobility of 6,200 cm2V−1s−1 is achieved in the strained‐relaxed n‐Ge0.88Sn0 ...

Overcome Limited Efficiency in All‐Perovskite Tandem Solar Cells Upon Light Management at Top Perovskite‐ Transparent Electrode Interfaces

Advanced Electronic Materials, EarlyView.
To further boost the PCE (power conversion efficiency) in all‐perovskite tandem solar cells (APTSCs), optimizing their optical structures is essential. In this study, it is found that the efficiency limitation in APTSCs is primarily due to reflective optical losses at the top perovskite interface.

The cauchy problem of a degenerate parabolic equation

Monatshefte f�r Mathematik, 1977
This note is concerned with the existence of a weak solution for a degenerate Cauchy problem of parabolic type in then-dimensional spaceRn. The degenerate property is in the sense that the matrix (aij(t,x)) involved in the differential operator is not necessarily positive definite.

Enhancing Thermoelectric Performance of Cd₃P₂ by Alloying with Dirac Material Cd₃As₂

Advanced Electronic Materials, EarlyView.
This study demonstrates that alloying Cd₃P₂ with Dirac material Cd₃As₂ significantly enhances its thermoelectric performance. Key improvements include increased carrier mobility, reduced effective mass, and lower deformation potential, resulting in a doubled power factor and improved thermoelectric efficiency, which renders this material applicable for

Local Fermi Level Engineering in 2D‐MoS2 Realized via Microcontact Printing of Self‐Assembled Monolayers for Next‐Generation Electronics

Advanced Electronic Materials, EarlyView.
2D transition metal dichalcogenides (TMDCs) are promising for next‐gen optoelectronics. Their sensitivity to surroundings affects their electronic behavior. Substrate surfaces are chemically engineered to locally dope and adjust the properties of single layer MoS2 FETs employing self‐assembled monolayers (SAMs) arranged in patterns.

Memory Manufacture Under Microgravity (MMuM): In‐Space Manufactured ZnO‐Based Resistive Random Access Memory for Emerging Computing Application

Advanced Electronic Materials, EarlyView.
This paper presented ZnO‐based crossbar RRAMs by electrohydrodynamic (EHD) printing technology under in‐space manufacture environment as microgravity (µG). The crossbar structures of Ag/ZnO/Ag are fabricated under earth with in‐space microgravity. With the microgravity effect, a significant electroforming forming voltage reduced 89.3% as a storage ...

Quasiconformal mappings and degenerate elliptic and parabolic equations

Le Matematiche, 1987
In this paper two Harnak inequalities are proved concerning a degenerate elliptic and a degenerate parabolic equation. In both cases the weight giving the degeneracy is a power of the jacobian of a quasiconformal mapping.
