โœฆ Synopsis

We demonstrate preferential and directional emission from a rolled up semiconductor microtube ring resonator with a quantum well embedded as an optically active material. The emission of resonant optical modes appears preferentially at the inside edge of the tube with a direction 60 to the tangent of the ring. The emission of leaky modes shows an entirely different behavior. Here, tangential emission seems to be preferred at both the inside and the outside edge.

In this paper, we have investigated the threshold energy required for photoelectric emission of electrons from a torroidal quantum ring of degenerate narrow-gap semiconductor. Current density due to electrons emitted from the ring illuminated by normal radiation has been calculated considering the e
