The standard example is etching of silicon by alternating reaction with chlorine (Cl2) and etching with argon ions (Ar). In the first step, shown in figure 20, firstly, Cl2 reactants are adsorbed onto the Si film surface; and then excess reactants are purged; following with Ar ions ...
(c) The van der Waals atomic radius, rvdW, is half the distance between the nuclei of two like atoms, such as argon, that are closely packed but not bonded. (d) This is a depiction of covalent versus van der Waals radii of chlorine. The covalent radius of Cl2 is half the distance...
1n), the larger atomic number of W (74) gives increased |E┴| compared to 2S (32), whereas in MoS2 (Fig. 1k, l), |E┴| around Mo (Z = 42) is only just slightly higher than that around 2S due to the similar total scattering cross section. The E┴ vector map (Fig. 1q...

The newly proposed ALD system exhibited typical ALD characteristics, such as self-limited film growth and linear dependency of the film growth on the number of ALD cycles, and showed a high growth rate of 0.072 nm/cycle on a thermally grown SiO2 substrate with a nearly zero incubation cycle....

Materials processing with atomic layer ({dollar}sim{dollar}1 A) precision is vital in a number of emerging technologies such as nanoelectronics. Despite the fact that significant advances have been made in thin film deposition with monolayer accuracy, methods to etch materials with atomic layer prec...
