Silver (Ag) single crystal substrates are widely used in various applications, including electronics, optics, and energy. They are known for their high electrical conductivity, low resistivity, high thermal conductivity, and low thermal expansion coefficient. These properties make Ag single crystal substrates a popular choice for device fabrication and as substrates for epitaxial growth of other materials.
Ag single crystal substrates are often used in applications such as the manufacture of thin film transistors, metal-semiconductor field-effect transistors, and surface acoustic wave devices. They are also used as substrates for the growth of high-quality thin films of semiconductors, such as III-V and II-VI compounds, for optoelectronic applications.
In addition to these applications, Ag single crystal substrates are also used as substrates for the growth of graphene, which is a two-dimensional material with unique electronic properties. The combination of the high electrical conductivity and low thermal expansion coefficient of Ag single crystal substrates and the high surface area of graphene makes it an ideal substrate for graphene-based electronic devices.
