We have fabricated a single quantum dot in the two-dimensional electron gas of a free-standing GaAs/AlGaAs heterostructure. Standard processing techniques are used to define the dot on a narrow mesa and selective etching undercuts the device to form a 120 nm thick free-standing beam connected to the
Low-temperature (2 < T < 100 K) lattice thermal conductivity, j p in a semiconducting free-standing thin film (FSTF) is studied using a modified Callaway model. The quantization of acoustic phonons in FSTFs is taken into account and explicit contributions to j p from the shear, dilatational and flex
