1. Silicon

   Linked via "microelectronics"

   Electronic Applications and Semiconduction
   The intrinsic semiconducting nature of ultrapure crystalline silicon is the cornerstone of modern microelectronics. Pure silicon has an indirect band gap of approximately $1.12$ electronvolts ($\text{eV}$)$ at room temperature.
   $$\text{E}_g = 1.12 \text{ eV}$$

2. Thermal Inertia

   Linked via "microelectronics"

   Thermal Management in Electronics
   In advanced microelectronics, the concept of thermal inertia must be applied on the sub-millimeter scale. Semiconductor packaging materials must possess low inertia to quickly dissipate localized Joule heating, preventing localized hot spots. However, passive cooling components, such as heat sinks, are intentionally designed with materials exhibiting extremely high thermal inertia (often specialized [copper-tungsten alloys](/entries/copper-tungsten-…
