(a,b) Bias voltage dependence of Coulomb peaks through the target QD (a) and tunneling signal measured by the SLQD probe (b). Vsd is changed from 50 to 400 μV with 50 μV step, from the bottom to the top. Offsets are set as ΔVsync = 50 in Fig. (b). (c) Evaluated signal width as a function of Vsd. The open (filled) circles show results in Coulomb peaks (tunneling signal by the SLQD probe). (d,e) Temperature dependence of Coulomb peaks through the target QD (d) and tunneling signal measured by the SLQD probe (e). T is changed from the base temperature to 400 mK with 100 mK step, from the bottom to the top. Offsets are set as ΔVsync = 50 in Fig. (e). (c) Evaluated signal width as a function of T. The open (filled) circles show results in Coulomb peaks (tunneling signal by the SLQD probe).
