Incorporating various electronic capabilities into a two-dimensional (2D) material enables the downsizing of multifunctional electronic devices, renewable energy storage devices, and data storage devices1–4 and is therefore a highly desirable objective. Most of the 2D materials have multiple properties like piezoelectricity, thermoelectricity, spintronics, and optoelectronics. Proper understanding of these properties will help to develop multipurpose electronic devices.

Sanjoy Mahajan's Back of the Envelope column included the 2019 paper “Fleeing the Quadratic Formula,”1 which argued that students gain more insight by approximating solutions than by direct application of an exact formula. He illustrated the use of this technique to estimate the depth of a well, given the time required to hear the splash after a stone is dropped into it. Since the result is dominated by the time for the stone to fall, an approximation is clearly useful.
