Highly Efficient Spin‐Orbit Torque Switching in a Topological Insulator/Chromium Telluride Heterostructure with Opposite Berry Curvature

open access: yesAdvanced Electronic Materials, EarlyView.
This study reports high spin‐torque efficiency (ΔHLJ=12.9×10−6mTA−1cm2$\frac{{{{\Delta}}{H_L}}}{J} = 12.9 \times {10^{ - 6}}{\mathrm{mT}}\;{{\mathrm{A}}^{ - 1}}{\mathrm{c}}{{\mathrm{m}}^2}$) and spin Hall conductivity (σSH=4.8×106ℏ2eΩ−1m−1${\sigma _{SH}} = 4.8 \times {10^6}\frac{\hbar }{{2e}}{{{\Omega}}^{ - 1}}{{\mathrm{m}}^{ - 1}}$), along with ...

Defect Density of States of Tin Oxide and Copper Oxide p‐type Thin‐film Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
The complete band‐to‐band defect density of states driving p‐mode operation in tin and copper oxide transistors is obtained through photoconduction microscopy over a 0.15 to 3.5 eV tunable laser range. These analytical maps of subgap defect density with the extracted TFT bandgaps, show how ideal p‐mode operation may be achieved in metal oxide thin‐film

Correlating the Photoshunt with Charge‐Collection Losses in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Quantifying charge extraction losses in organic solar cells is crucial for understanding the origin of power losses and, consequently, for improving the performance. An analytical framework is presented that utilizes a readily available observable photoshunt and its correlation with light intensities for evaluating charge transport properties of a ...
