Single Dopants in Semiconductors
The sensitive dependence of a semiconductor’s electronic, optical, and magnetic properties on dopants has provided an extensive range of tunable phenomena to explore and apply to devices. Recently it has become possible to move past the tunable properties of an ensemble of dopants and to identify the effects of a solitary dopant on commercial device performance as well as locally on the fundamental properties of a semiconductor. New applications have become available that require the discrete character of a single dopant, such as single-spin devices in the area of quantum information or single-dopant transistors. Dramatic advances in the past decade towards observing, controllably creating and manipulating single dopants, as well as their application in novel devices have allowed opening the new field of solotronics (solitary dopant optoelectronics).

Famous quotes containing the word single:
“What has influenced my life more than any other single thing has been my stammer. Had I not stammered I would probably ... have gone to Cambridge as my brothers did, perhaps have become a don and every now and then published a dreary book about French literature.”
—W. Somerset Maugham (1874–1965)
