Thermal Conductivity of Common Semiconductors
The thermal conductivity of semiconductors refers to their ability to conduct heat. Semiconductors typically have lower thermal conductivity compared to metals but higher than insulators. The following table provides a comprehensive list of thermal conductivity values for common semiconductors at room temperature (approximately 20°C or 68°F).
