Lead-Free Halide Double Perovskites via Heterovalent

Lead-based halide perovskites are emerging as the most promising class of materials for next-generation optoelectronics; however,despite the enormous success of lead-halide perovskite solar cells,the issues of stability and toxicity are yet to be resolved.Here we report on the computational design and the experimental synthesis of a new family of Pb-free inorganic halide double perovskites Mercouri G.Kanatzidis - PublicationsHigh performance Na-doped PbTe-PbS thermoelectric materials electronic density of states modification and shape-controlled nanostructures.Journal of the American Chemical Society.133 16588-97.PMID 21902270 DOI 10.1021/ja206380h 1 2011NTT Basic Research LaboratoriesABSTRACT We have measured the conductance and shot noise of superconductor-normal metal (S-N) junctions between a niobium (Nb) film and a two-dimensional electron gas (2DEG),formed in an InAs-based semiconductor heterostructure.Adjacent to the junction,the 2DEG is shaped into a sub-micrometer beam splitter.

For tubes barely touching the Hg surface,the conductance is low (typically G(V=0)~0.10.5G 0); G(V) may maximize around V=1.52 V or continue to increase linearly depending on the MWNTHg contact.For good contacts the maximum low-bias conductance is 1G 0.Non-conducting tubes are observed having a low-bias conductance smaller than 10 New Journal of Physics,Volume 7,2005 - IOPscienceThe oxygen-p orbitals which pd-bond to the cations are the same as those which pd-bond to the transition-metal t 2g orbitals.As a consequence,the Wannier functions for the t 2g band exhibit residual covalency between the transition-metal t 2g,the large cation-d,and the oxygen-p states.Previous123456NextSynthesis,Structure,and Properties of SingleWalled Dec 04,2009·Great interest in singlewalled carbon nanotubes (SWCNTs) derives from their remarkable electrical,thermal,optical,and mechanical properties together with their lower density,which promise extensive and unique applications.Much progress has been achieved in the fundamental and applied investigations of SWCNTs over the past decade.At the same time,many obstacles still
