ALD Material Atomic layer deposition (ALD) is a chemically self-limiting deposition technique that is based on the sequential use of a gaseous chemical process. A thin film (as fine as -0.1 Å per cycle) results from repeating the deposition sequence as many times as needed to reach a certain thickness. The major characteristic of the films is the resulting conformality and the controlled deposition manner. Precursor selection is key in ALD processes, namely finding molecules which will have enough reactivity to produce the desired films yet are stable enough to be handled and safely delivered to the reaction chamber.

Tetramethyltin (TMT) is a model system that has been used to study the reactivity of hydrogen fluoride with sodium carbonate. This reaction has been studied using fluorescence spectrometry in order to determine the high values for analytical methods. Tetramethyltin is also known to inhibit replication by inhibiting the activity of RNA-dependent DNA polymerase, which is required for DNA synthesis. The kinetic energy of this compound is also known as group p2, and kinetic data has been obtained on this compound.
