Patent number: 11563144Abstract: Semiconductor structures and methods for forming those semiconductor structures are disclosed. For example, a semiconductor structure with a p-type superlattice region, an i-type superlattice region, and an n-type superlattice region is disclosed. The semiconductor structure can have a polar crystal structure with a growth axis that is substantially parallel to a spontaneous polarization axis of the polar crystal structure. In some cases, there are no abrupt changes in polarisation at interfaces between each region. At least one of the p-type superlattice region, the i-type superlattice region and the n-type superlattice region can comprise a plurality of unit cells exhibiting a monotonic change in composition from a wider band gap (WBG) material to a narrower band gap (NBG) material or from a NBG material to a WBG material along the growth axis to induce p-type or n-type conductivity.Type: GrantFiled: September 3, 2021Date of Patent: January 24, 2023Assignee: Silanna UV Technologies Pte LtdInventors: Petar Atanackovic, Matthew Godfrey

Publication number: 20200318458Abstract: Plug and plug seat valves with selective orientation and engagement systems permit plugs to pass through a series of identically or similarly sized seats without the plugs mating with any of such seats before passing therethrough. Orientation systems may be employed in these valves such that the plug passes through each plug seat in a specific orientation in relation to the seat. The orientation systems may employ a steering track, such as rotational guide, to establish a desired relationship between features around the outer surface of the plug and the inner surface of the plug seat. Engagement systems may comprise one or more retractable elements on the plug which complement a receiving element of the plug seat. The orientation system may misalign the elements of the engagement system allowing a plug to pass an otherwise complementary plug seat.Type: ApplicationFiled: April 4, 2019Publication date: October 8, 2020Inventors: Matthew Godfrey, William Sloane Muscroft
