NIST helps develop new method to attach long-chain aliphatic molecules to silicon.
Direct attachment of organic molecules to the silicon surface is of increasing importance for emerging molecular electronics applications as devices incorporating molecules chemically bonded to silicon are amenable to integration with existing Si processing techniques. In addition, the chemical bond between Si and organic molecules is stronger and, therefore, expected to be more stable than the metal-molecule bond typically used in the assembly of molecular electronic devices. However, forming this Si-molecule bond to create self-assembled monolayers can be difficult. Costly and time consuming ultra-high vacuum techniques are often used to attach molecules to Si.
