A high open-circuit voltage betavoltaic cell based on a GaN pin homojunction is demonstrated. A process of doping compensation has been developed to achieve high resistance i-GaN film for betavoltaics. Under 0.5 mCi 63Ni source irradiation, the open-circuit voltage of the fabricated GaN pin homojunction betavoltaic cell was measured as high as 1.65 V. A fill factor of 54% and a 2.7% lower bound on...
A new approach of monolithic integration of InP based heterostructures on silicon is proposed, based on the plastic compliant behavior of the InP/Gd2O3(111) heterointerface. When grown on a crystalline Gd2O3/Si(111) buffer, InP takes its bulk lattice parameter as soon as the growth begins, allowing the monolithic growth of good quality InAsP/InP heterostructures on Si, as attested by room-temperature...
Coherent nonlinear optical measurements on single charged GaAs quantum dots show both bright and dark transitions in the Voigt configuration. Preliminary measurements give the lower limit of spin dephasing time (T2) as 13 nsec
This work demonstrates the coherent optical creation and detection of the coherence between the states of a single electron spin in a charged quantum dot
