ABSTRACTThis paper reviews the diverse methods used to achieve doping during MBE of Si and SiGe, and the incorporation processes involved. The optimum choice of dopant and methodology depends on the most appropriate growth conditions for a given structure. At growth temperatures exceeding 750°C, Potential Enhanced n-type doping of coevaporated Sb is capable of achieving high resolution structures, at doping levels up to mid-1019 cm−3. At lower temperatures, such as those most suited to SiGe growth, Sb-doping becomes a formidable challenge, due to the high accumulated equilibrium coverages required. Low energy ion implantation appears to be the favoured route for good control, p-type B-doping can readily be achieved by coevaporation of compounds or, to avoid oxygen incorporation at low temperatures, the element. A “designer” chart for B-doping of Si is presented.

AbstractThe in-situ aqueous synthesis of ZnO nanorods doped with Sb is presented. To control the inclusion of Sb into the ZnO nanorods structure ethylene glycol (EG) is added to the reaction solution. The addition of EG reduces the rate at which Sb is included in the ZnO rods and produces nanorods with a morphology that is similar to the undoped rods. This is contrary to the rods produced with Sb in the absence of EG which produce a less well ordered structure. An I/V curve taken from individual rods indicates a change in the diode behaviour. The change in I/V behaviour is associated with a change from the natural n-type behaviour of ZnO to a p-type behaviour due to the Sb doping.

One means of enhancing the performance of thermoelectric materials is to generate secondary nanoprecipitates of metallic or semiconducting properties in a thermoelectric matrix, to form proper band bending and, in turn, to induce a low-energy carrier filtering effect. However, forming nanocomposites is challenging, and proper band bending relationships with secondary phases are largely unknown. Herein, we investigate the in situ phase segregation behavior during melt spinning with various metal elements, including Ti, V, Nb, Mo, W, Ni, Pd, and Cu, in p-type Bi0.5Sb1.5Te3 (BST) thermoelectric alloys. The results showed that various metal chalcogenides were formed, which were related to the added metal elements as secondary phases. The electrical conductivity, Seebeck coefficient, and thermal conductivity of the BST composite with various secondary phases were measured and compared with those of pristine BST alloys. Possible band alignments with the secondary phases are introduced, which could be utilized for further investigation of a possible carrier filtering effect when forming nanocomposites.
