Latest Patents
Namba's latest patents include an innovative electron emitting device that features a structure designed for efficient electron emission. This device comprises a substrate made of n-type diamond, with a pointed projection that includes a base and an electron emission portion. The base is also made of n-type diamond, while the electron emission portion is constructed from p-type diamond. The design allows for optimal electron emission from the tip of the projection, with a length of 100 nm or less from the tip to the interface between the two types of diamond.
Another notable patent involves a method for fabricating n-type semiconductor diamond. This process entails the formation of an n-type diamond epitaxial layer by processing a single-crystalline {100} diamond substrate to create a {111} plane. The diamond is then allowed to grow epitaxially while n-doping the {111} plane. This method enables the creation of various semiconductor junction types, including pn junctions, pnp junctions, npn junctions, and pin junctions.
