Abstract = {We study the electron transport properties of gated quantum dots formed in InGaAs/InP quantum well structures grown by chemical-beam epitaxy on prepatterned substrates. Quantum dots form directly underneath narrow gates due to potential fluctuations. We measure the Coulomb-blockade diamonds in the few-electron regime of a single dot and observe photon-assisted tunneling peaks under microwave irradiation. A singlet-triplet transition at high magnetic field and Coulomb-blockade in the quantum Hall regime are also observed. {\copyright} 2011 American Institute of Physics.},
