epitaxis. n. (General Physics) the growth of a thin layer on the surface of a crystal so that the layer has the same structure as the underlying crystal. epitaxial, epitaxic adj.
Epitaxial Growth of Ge on Si with Low Dislocation Density High-quality epitaxial growth of Ge on Si has been realized by using an ultrahigh-vacuum chemical vapor deposition (UHV/CVD) technique. Langdo et al. [ 27 ] showed that pure Ge grown selectively on SiO 2 /Si substrates in 100 nm holes is highly perfect at the top surface compared to conventional Ge lattice-mismatched growth on planar Si
• For most thin film applications (hard and soft coatings, optical coatings, protective coatings) it is of little importance. • However, for semiconductor thin film technology it is crucial. semiconductor samples during epitaxial crystal growth. Combining the two techniques allows us to make "smart" pyrometry measurements in which the sample emissivity is measured rather than assumed. This change overcomes one of the largest limitations in the application of pyrometry to thin film deposition or etching.
epitaxial, epitaxic adj. Epitaxial growth is the ordered or arranged atomic growth of a single crystalline material over the single crystalline substrate. transportation of the materials, the epitaxial growth takes place on the substrate [16]. The temperature of the substrate plays a vital rule for chemical reactions and cracking of the precursors.
Topographical data of this type of growth presents as a perfect tessellation of crystal edges. Here, the epitaxial growth of highly aligned MoS 2 grains is reported on a twofold symmetry a‐plane sapphire substrate.

The term epitaxy comes from the Greek roots --- epi, meaning "above", and taxis, meaning "in ordered manner". Epitaxial Crystal Growth: Methods and Materials 14.1 Liquid-Phase Epitaxy (LPE). Liquid-phase epitaxy ( LPE ) is a mature technology and has unique features that make 14.2 Metal Organic Chemical Vapor Deposition. The technique of MOCVD was first introduced in the late 1960s for the 14.3 Epitaxial growth is the ordered or arranged atomic growth of a single crystalline material over the single crystalline substrate.

We report the two-step epitaxial growth of lateral WSe2-MoS2 heterojunction, where the edge of WSe2 induces the epitaxial MoS2 growth despite a large lattice mismatch. The epitaxial growth process offers a controllable method to obtain lateral heterojunction with an atomically sharp interface.

Epitaxy refers to a type of crystal growth or material deposition in which new crystalline layers are formed with one or more well-defined orientations with respect to the crystalline substrate. The deposited crystalline film is called an epitaxial film or epitaxial layer. Epitaxial Crystal Growth: Methods and Materials 14.1 Liquid-Phase Epitaxy (LPE). Liquid-phase epitaxy ( LPE ) is a mature technology and has unique features that make 14.2 Metal Organic Chemical Vapor Deposition.
