Merging Nanowires and Formation Dynamics of Bottom‐Up Grown InSb Nanoflakes

Formation of long single quantum dots in high quality InSb nanowires grown by molecular beam epitaxy.

We report on realization and transport spectroscopy study of single quantum dots (QDs) made from InSb nanowires grown by molecular beam epitaxy (MBE). The nanowires employed are 50-80 nm in diameter and the QDs are defined in the nanowires between the source and drain contacts on a Si/SiO2 substrate. We show that highly tunable QD devices can be realized with the MBE-grown InSb nanowires and th...

Electrical properties of InAs1xSbx and InSb nanowires grown by molecular beam epitaxy

Growth of high quality, epitaxial InSb nanowires

The growth of InSb nanowires on an InSb(1 1 1) substrate in a closed system is described. A high density InSb nanowires was grown by the use of InSb substrates in a torch sealed quartz tube at a temperature of 400 1C, using a 60 nm size gold colloid catalyst. The typical diameter of the InSb nanowires was 80–200 nm and they consisted of nearly equal atomic percent of In and Sb. Transmission ele...

Hard Superconducting Gap in InSb Nanowires

Topological superconductivity is a state of matter that can host Majorana modes, the building blocks of a topological quantum computer. Many experimental platforms predicted to show such a topological state rely on proximity-induced superconductivity. However, accessing the topological properties requires an induced hard superconducting gap, which is challenging to achieve for most material sys...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
