Hydrogen-terminated silicon surface
open-in-new
<p>Hydrogen-terminated silicon surface is a chemically passivated <a href="/facts/Silicon/cgWx0hdr">silicon</a> <a href="/facts/Wafer_(electronics)/lCBJAoUL">substrate</a> where the surface Si atoms are bonded to hydrogen. The hydrogen-terminated surfaces are hydrophobic, luminescent, and amenable to chemical modification. Hydrogen-terminated silicon is an intermediate in the growth of bulk silicon from <a href="/facts/Silane/XNevDLgE">silane</a>: This termination is significant in the semiconductor industry due to its role in preventing oxidation and contamination of silicon surfaces, which is crucial for various applications including microelectronics and nanotechnology. </p> SiH4 → Si + 2 H2
