Inthe last several years considerable efforts have been devoted todeveloping Bose-Einstein-condensate-based devices for applications such as fundamental research, precisionmeasurements, and integrated atom optics. Such devices, capable of complexfunctionality, can be designed from simpler building blocks as isdone in microelectronics. One of the most important components ofmicroelectronics is a transistor. We demonstrate that a Bose-Einstein condensatein a three-well potential structure where the tunneling of atomsbetween two wells is controlled by the population in thethird shows behavior similar to that of an electronic field-effecttransistor. Namely, it exhibits switching and both absolute and differentialgain. The role of quantum fluctuations is analyzed, and estimatesof the switching time and parameters for the potential arepresented.
