    摘要: A junction suitable for incorporation in diamond electronic devices, such as field effect transistors, U-V photodetectors, capacitors, charge-coupled devices, etc., comprising a double layer structure deposited on the semiconducting diamond film of the electronic device, wherein the double layer structure consists of a layer of intrinsic diamond and a layer of a carrier blocking material. The carrier blocking materials is characterized by a band structure discontinuous with that of diamond resulting in the formation of a depletion layer at the interface. A contact is then formed on this double layer structure.

    摘要: A diamond-based structure includes a substrate, an adhesive material on a face of the substrate, and an array of spaced apart diamond mesas bonded to the substrate by the adhesive material. In particular, each of the diamond mesas can have a growth surface adjacent the substrate and an interfacial surface opposite the substrate, and the interfacial surface can be smooth relative to the growth surface. This structure can be fabricated by providing a sacrificial substrate, forming a plurality of diamond mesas on a face of the sacrificial substrate, bonding the diamond mesas to a transfer substrate, and removing the sacrificial substrate. Accordingly, the interfacial surfaces of the diamond, which are formed adjacent the sacrificial substrate and then exposed by removing the substrate are smooth.

    摘要: A high frequency Surface Acoustic Wave (SAW) device includes a highly oriented diamond layer adjacent a piezoelectric layer. In one embodiment, laterally spaced apart piezoelectric layers or portions confine propagation of the wave within the diamond layer. Interdigitated electrodes may be provided by electrically conductive metal lines and/or by heavily doped surface portions of the diamond layer. Undesirable reflections may be reduced by providing the piezoelectric layer with opposing ends canted at an angle from orthogonal to the axis of surface acoustic wave propagation. The surface acoustic wave device may be used as a filter, amplifier, convolver, and phase shifter. Methods for making the surface acoustic wave device are also disclosed.

    摘要: A diamond semiconductor device with a carbide interlayer includes a diamond layer having a semiconducting diamond region of first conductivity type therein and an insulated gate structure on a face of the diamond layer. The relatively thin carbide interfacial layer is provided between the insulated gate structure and the diamond layer in order to inhibit the formation of electrically active defects, such as interface states at the face. By inhibiting the formation of interface states at the face, the carbide interfacial layer suppresses parasitic leakage of charge carriers from the diamond layer to the insulated gate structure. The carbide interfacial layer can be intrinsic silicon carbide or an intrinsic refractory metal carbide (e.g., TiC or WC) or the layer can be of opposite conductivity type to thereby form a P--N heterojunction with the diamond layer. The carbide interfacial layer and the insulated gate structure can be used in a variety of diamond electronic devices such as MIS capacitors, enhancement-mode and buried-channel insulated-gate field effect transistors (IGFETs), surface-channel and buried-channel charge-coupled devices (CCDs), detectors, heterojunction devices, and other related field effect devices. Related fabrication methods are also disclosed.
