Researchers Discover Causes for Quantum Property of Semiconductor Quantum Rings

Technology

Excellent quantum properties could be achieve through the breaking of rotational symmetry in ring-shaped nanoparticle. Particles that come with nanometer in size are spearheading the scientific researches of present times. These nanoparticles come in various sizes like vesicles, rods, cubes, and spheres. Despite being so tiny, these particles display such quantum mechanical characteristics that cannot be seen in larger objects, and hence it becomes an important topic for research.

Scientists at the Center for Nanoscale Materials, a U.S. Department of Energy Office of Science User Facility situated at Department of Energy Office’s Argonne National Laboratory recently published a piece of research on Nature Communications journal. The publication finds out that the reason for quantum property of semiconductor quantum rings. Such a characteristic is likely to find abundant use in communication, computing, and storage of quantum information.

Direction of Light Emission altered through Breaking of Rotational Symmetry

Throughout this project, the researchers at Center for Nanoscale Materials have joined forces with their counterparts from National Research Council in Canada, University of Ottawa, Ludwig Maximilian University of Munich, and University of Chicago.

The research team collected circular rings that are made of cadmium selenide, which is a semiconductor.Therefore,this semiconductor comes handy for the purpose of increasing donut-shaped nanoparticles. These quantum rings come with two-dimensional structures. These crystalline substances comprise some atomic layers. These semiconductors do have some benefits. When agitated with a laser the semiconductor start emitting photons.

 It is while breaking the ideal rotational symmetry of the shape of the donut and it makes them a little elongated in shape. Xuedan Ma is an assistant scientist at Center for Nanoscale Materials. Researcher Ma opined that through breaking of this symmetry, direction of emission of light could be altered. Researchers could tune the light emission so as to efficaciously gather single photons. The photons in the light emits in one particular direction rather than spreading in all of the directions.
