FIG. 21.6 A modeled pendulum in Algodoo with dynamic vector arrows as they change throughout the pendulum swing—velocity in black, external forces on the bob in white, and the sum of all external forces in green (left). A constructed “car” in Algodoo with motors on the front and rear wheels ascends a slope (right). Dynamic vector arrows are displayed for the orange box, while the graph above shows the time dependence of the box's gravitational potential energy.

FIG. 8.27 Temperature-dependent reverse leakage characteristics of a near-ideal β-Ga2O3 SBD. The reverse leakage current (JR) is a sum of TE current (JTE) that captures over-the-barrier current and TFE current (JTFE) that captures below-the-barrier tunneling current under low-to-moderate surface electric fields at the Schottky interface. As the surface field increases or the temperature decreases, the dominant reverse leakage mechanism transitions from TE to TFE. Reprinted with permission from Li et al., J. Appl. Phys. 131 (1), 015702 (2022). Copyright 2022 AIP Publishing LLC. More about this image found in Temperature-dependent reverse leakage characteristics of a near-ideal β-Ga...
