Abstract
Methods of selectively synthesizing n-tetrasilane are disclosed. N-tetrasilane is prepared by pyrolysis of silane (SiH), disilane (SiH), trisilane (SiH), or mixtures thereof. More particularly, the disclosed synthesis methods tune and optimize the n-tetrasilane:i-tetrasilane isomer ratio. The isomer ratio may be optimized by selection of process parameters, such as temperature, residence time, and the relative amount of starting compounds. The disclosed synthesis methods allow facile preparation of n-tetrasilane.
