FIG. 1.

Galvanic (a) versus nongalvanic (b) QDT. In (a), temperature is determined by the linewidth of Coulomb-blockade peaks, obtained from a transport measurement. In (b), from the average occupation of the dot, read out in a nongalvanic fashion by a QPC placed nearby.

FIG. 2.

Steady-state electron temperature versus phonon bath temperature , for domains of different areas, in the presence of a QDT, a QDR, or both. Parasitic heat loads on the system are not taken into account.

FIG. 3.

(a) QPC current I versus gate voltage for different values of the domain temperature ; a steeper sawtooth corresponds to a lower . Inset: current gain versus for three different QPC working points. (b) Transconductance versus for the same set of temperatures as in (a); a sharper peak corresponds to a lower . Inset: Transconductance gain versus [same working points as in (a)]. Parameters: . In the main panels, . In the insets, the gains are evaluated at optimal points. For , we take into account 1 μV fluctuations of . For , the curves are those expected for a lock-in measurement with 1 μV signal amplitude.
