Bulk Silicon - an overview | ScienceDirect Topics

Bulk semiconductors, especially silicon, form the backbone of modern electronics and computing. Bulk silicon however is a very dull material, being an especially poor emitter of light, turning added energy into heat. This makes integrating electronic and photonic circuits a challenge. There have been several proposals to alleviate this problem.
