Temperature and Magnetic Field Effects on the Transport Controlled Charge State of a Single Quantum Dot

<p>Abstract</p> <p>Individual InAs/GaAs quantum dots are studied by micro-photoluminescence. By varying the strength of an applied external magnetic field and/or the temperature, it is demonstrated that the charge state of a single quantum dot can be tuned. This tuning effect is sh...
