Premelting at Defects Within Bulk Colloidal Crystals [PDF]
Science, 2005 Premelting is the localized loss of crystalline order at surfaces and defects at temperatures below the bulk melting transition. It can be thought of as the nucleation of the melting process. Premelting has been observed at the surfaces of crystals but not within.

Structural defects in bulk GaN
Journal of Crystal Growth, 2014Abstract Transmission Electron Microscopy (TEM) studies of undoped and Mg doped GaN layers grown on the HVPE substrates by High Nitrogen Pressure Solution (HNPS) with the multi-feed-seed (MFS) configuration are shown. The propagation of dislocations from the HVPE substrate to the layer is observed. Due to the interaction between these dislocations in

Controlling Bulk Conductivity in Topological Insulators: Key Role of Anti-Site Defects
Advanced Materials, 2012 Intrinsic topological insulators are realized by alloying Bi2Te3 with Bi2Se3. Angle-resolved photoemission and bulk transport measurements reveal that the Fermi level is readily tuned into the bulk bandgap.

Trapped Fractional Charges at Bulk Defects in Topological Insulators
Nature, 2021Topological crystalline insulators (TCIs) can exhibit unusual, quantized electric phenomena such as fractional electric polarization and boundary-localized fractional charge1-6. This quantized fractional charge is the generic observable for identification of TCIs that lack clear spectral features5-7, including ones with higher-order topology8-11.

Bulk Buying of Possibly Defective Items
Journal of the Operational Research Society, 1984Summary: The paper examines buying where faulty items are returned repeatedly until the entire order is obtained defect-free, as is typified by mail- order buying. The advantage of bulk buying is investigated theoretically both when the probability of being defective is assumed constant and when it is allowed to vary.

Bulk Defect Chemistry of PCFC Cathode Materials: Discussion of Defect Interactions
ECS Meeting Abstracts, 2017In order to extend the reactive zone for oxygen reduction to water beyond the gas/electrode/electrolyte three phase boundary, cathode materials for proton conducting ceramic fuel cells should exhibit a certain proton conductivity, exceeding 10-5 S/cm [1]. Proton uptake into (Ba,Sr,La)(Mn,Fe,Co)O3- d perovskites considered as cathode
