Polymorphism of Resorcinol Explored by Complementary Vibrational Spectroscopy (FT-RS, THz-TDS, INS) and First Principles Solid-State Computations (Plane-Wave DFT)

The polymorphism of resorcinol has been complementary studied by combining Raman, time-domain terahertz and inelastic neutron scattering spectroscopy with modern solid-state density functional theory (DFT) calculations. The spectral differences, emerging from the temperature-induced structural phase transition, have been successfully interpreted with an emphasis on the low-wavenumber range. The given interpretation is based on the plane-wave DFT computations, providing an excellent overall reproduction of both wavenumbers and intensities and revealing the source of the observed spectral differences. The performance of the generalized gradient approximation (GGA) functionals in prediction of the structural parameters and the vibrational spectra of the normal-pressure polymorphs of resorcinol has been extensively examined. The results show that standard PBE along with its ‘hard’ revised form tend to be superior if compared to the ‘soft’ GGA approximation.

TeraView announces being a proud sponsor of this year’s IRMMW-THz conference

TeraView are glad to announce its continued support of the terahertz research community by being a proud sponsor of this year’s IRMMW-THz conference hosted by Professor Emma MacPherson in Hong Kong! 

The International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), is the oldest and largest continuous forum devoted to the science and technology of long-wavelength radiation. The scope of the conference includes all scientific and technological activities from millimeter-waves to the THz regime and on to the far-infrared region of the electromagnetic spectrum. This covers a very wide range of disciplines, encompassing everything from micro- and nano-scale devices and structures to large-scale accelerators and tokamaks and their applications. Presentations at this conference address issues ranging from basic physics, chemistry, electrical engineering and materials science to problems in high frequency circuits and systems, communications, antennas and optics, imaging and spectroscopy, and much, much more.

The conference will be held 23-28 August 2015 at the Chinese University of Hong Kong. For more information please visit: http://bme.ee.cuhk.edu.hk/thzgroup/irmmw2015/

TeraHertz: New opportunities for industry - 3-5 February 2015

TeraHertz (THz), the frequencies between electronics and optics,
was until recently the last unexploited part of the electro-
magnetic spectrum. The harnessing of THz-based technologies has the potential of impacting globally a vast number of industries, like both electronics in the 70’s and optics in the 80’s did.

THz applications span over a wide array of fields, including:

Quality Control and Non-destructive testing
Surface analysis
Chemical and Bio-Medical analysis
Filling the TeraHertz “gap” has led to unprecedented creativity in the development and commercialization of TeraHertz sources, transmission components and detectors.

This year’s edition will focus on THz materials measurements and applications.

Registration deadline: 23 January 2015
