Graphene for Emission of Terahertz Radiation

open access: yes, 2018
Graphene is a two-dimensional crystal consisting of a monatomic layer of carbon atoms. Electrons and holes in graphene behave as quasi-relativistic particles with zero effective mass and large (as compared to semiconductors) Fermi velocity. These unique physical properties can be used for designing detectors, emitters and modulators of terahertz ...

A Sophisticated Terahertz Photonic Crystal Fiber Sensor Design for Highly Accurate Detection of Kerosene Mixtures

open access: yesAdvanced Physics Research, EarlyView.
A novel Photonic Crystal Fiber sensor with an octagonal cladding and hollow core is developed to detect kerosene adulteration. At 2.2 THz, the sensor achieves 96.80% relative sensitivity, an effective mode loss of 0.00667 cm⁻¹, and minimal confinement loss (6.78 × 10⁻8 dB m−1).

Electronic and Magnetic Properties of Ferrous Iron in a True Square‐Planar Molecular Environment

open access: yesChemistry – A European Journal, EarlyView.
Spin Hamiltonian parameters of an iron(II) phthalocyanine are obtained by pNMR, THz‐EPR, and quantum chemical calculations. Large zero field splitting and the peculiar g‐tensor pattern originate from mixing of the 3A2g ground state with two 3Eg‐excited states of almost the same energy. This forms the basis for correlations between magnetism, structure,
