Embodiments of the present invention generally relate to methods of epitaxially growing boron-containing structures. In an embodiment, a method of depositing a structure comprising boron and a Group IV element on a substrate is provided. The method includes heating the substrate at a temperature of about 300° C. or more within a chamber, the substrate having a dielectric material and a single crystal formed thereon. The method further includes flowing a first process gas and a second process gas into the chamber, wherein: the first process gas comprises at least one boron-containing gas comprising a haloborane; and the second process gas comprises at least one Group IV element-containing gas. The method further includes exposing the substrate to the first and second process gases to epitaxially and selectively deposit the structure comprising boron and the Group IV element on the single crystal.

Materials containing picocrystalline quantum dots that form artificial atoms are disclosed. The picocrystalline quantum dots (in the form of born icosahedra with a nearly-symmetrical nuclear configuration) can replace corner silicon atoms in a structure that demonstrates both short range and long-range order as determined by x-ray diffraction of actual samples. A novel class of boron-rich compositions that self-assemble from boron, silicon, hydrogen and, optionally, oxygen is also disclosed. The preferred stoichiometric range for the compositions is (B.sub.12H.sub.w).sub.xSi.sub.yO.sub.z with 3≤w≤5, 2≤x≤4, 2≤y≤5 and 0≤z≤3. By varying oxygen content and the presence or absence of a significant impurity such as gold, unique electrical devices can be constructed that improve upon and are compatible with current semiconductor technology.

A method is provided. The method includes the following steps: introducing a first physical vapor deposition (PVD) target and a second PVD target in a PVD system, the first PVD target containing a boron-containing cobalt iron alloy (FeCoB) with an initial boron concentration, and the second PVD target containing boron; determining parameters of the PVD system based on a target boron concentration larger than the initial boron concentration; and depositing a FeCoB film on a substrate according to the parameters of the PVD system.

Described are lanthanide-containing metal coordination complexes which may be used as precursors in thin film depositions, e.g. atomic layer deposition processes. More specifically, described are homoleptic lanthanide-aminoalkoxide metal coordination complexes, lanthanide-carbohydrazide metal coordination complexes, and lanthanide-diazadiene metal coordination complexes. Additionally, methods for depositing lanthanide-containing films through an atomic layer deposition process are described.
