Business & Innovation Network (BIN) - Ribeirão Preto, Brazil - November 12 – 14th 2013

TeraView's Ian Grundy was recently at the Business & Innovation Network (BIN) event in Ribeirão Preto, Brazil

Here's what Ian had to say on the event:

What a great event!

At the invitation of the organizing committee Ian Grundy, SVP sales at TeraView was pleased to attend the above event to talk about TeraViews technology and the process/experience of spinning technology companies out from universities.

The event was attended by a mix of academics and spin out companies from Europe and N. and S. America. The aim was simply to build networks and to do some business!

The weather was hot and the people great.

A number of conversations are now under-way and TeraView would like to thank everyone for their hospitality and help. Next year the event will be held in the UK, in Sheffield, and we look forward to attending.

Detailed non-destructive evaluation of UHMWPE composites in the terahertz range

Optical and Quantum ElectronicsDOI 10.1007/s11082-013-9836-4

N. Palka, D. Miedzinska


We report on the terahertz analysis of an internal structure of an ultra-high molecular weight polyethylene (UHMWPE) composite material, which is based on the HB10-tape from Dyneema®. This type of composite is very hard and resistant and therefore it is often used to manufacture personal armors such as bulletproof vests and helmets. The multilayer structure of the UHMWPE composite was investigated by means of a raster scanning time domain spectroscopy technique in a reflection configuration. The mechanism of the formation of many shifted in time THz pulses (reflected from the internal layers of the sample) originates from the periodic modulation of the refractive index along the propagation of the radiation. This modulation is connected with alternate layers of fibers, each having different direction (perpendicular to each other). As a result we obtained the detailed three dimensional profile of the 3.3-mm thick sample with all 74 layers clearly visible. Thicknesses of all layers, having around 45 μm each, were determined. Moreover, it is also possible to identify internal defects i.e. delaminations in the internal structure of this composite material.

Professor Sir Michael Pepper FRS, will be awarded the Dirac Medal and give the 2013 Dirac Public Lecture.

Semiconductor Nanostructures and Quantum Phenomena

Sir Michael Pepper
Industry innovation has developed a combination of electron beam lithography and advanced semiconductor growth. This has stimulated interest in discovering more about the basic properties of semiconductor nanostructures.

Professor Pepper will give the Dirac Lecture on advanced semiconductor growth technology. The Lecture will show how this technology, which was developed for the information technology industry, has allowed the creation of new types of structures for investigating the quantum aspects of electron transport. It will also show how the dimensionality which is experienced by the electrons can be reduced from 3 to 2 to 1 and then to 0.

History of the Dirac Lecture:

The Dirac Medal for the Advancement of Theoretical Physics is awarded by the UNSW and the Australian Institute of Physics. The Lecture and the Medal commemorate the visit to the university in 1975 of Professor Dirac, who gave five lectures. The lectures were subsequently published as a book Directions of Physics. Professor Dirac donated the royalties from this book to the University for the establishment of the Dirac Lecture and Prize. The prize includes a silver medal and honorarium. It was first awarded in 1979.

Professor Pepper will also be awarded an Honorary Degree on the evening. Please join us in congratulating Professor Pepper.

Influence of high-pressure treatment on charge carrier transport in PbS colloidal quantum dot solids

Seung Jin Heo,   Seokhyun Yoon,   Sang Hoon Oh,   Doo Hyun Yoon and    Hyun Jae Kim -Nanoscale, 2013


We investigated the effects of high-pressure treatment on charge carrier transport in PbS colloidal quantum dot (CQD) solids. We applied high pressure to PbS CQD solids using nitrogen gas to reduce the inter-dot distance. Using this simple process, we obtained conductive PbS CQD solids. Terahertz time-domain spectroscopy was used to study charge carrier transport as a function of pressure. We found that the minimum pressure needed to increase the dielectric constant, conductivity, and carrier mobility was 4 MPa. All properties dramatically improved at 5 MPa; for example, mobility increased from 0.13 cm2 V-1 s-1 at 0.1 MPa to 0.91 cm2 V-1 s-1 at 5 MPa. We propose this simple process as a nondestructive approach for making conductive PbS CQD solids that are free of chemical and physical defects.
