Critical temperatures of 70%Pb(Mg1∕3Nb2∕3)O3–30%PbTiO3 thin films investigated by dielectric, ferroelectric, and structural measurements

X.J. Meng, Denis Remiens, Mickael Detalle, B. Dkhil, Jl. Sun, Jh. Chu

The authors have investigated the temperature dependence of the ferroelectric, dielectric, and structural properties of 70%Pb(Mg1∕3Nb2∕3)O3–30%PbTiO3 thin films. Two critical temperatures were evidenced. The first one occurring around 410K corresponds to the bulk paraelectric-ferroelectric phase...

Integrated terahertz TEM horn antenna

Emilien Peytavit, Jean-Francois Lampin, Tahsin Akalin, L. Desplanque

A terahertz transverse electromagnetic horn antenna (THz-TEMHA) monolithically integrated on a gallium arsenide substrate has been studied by means of subpicosecond pulses generated and measured on a 50 Ω coplanar waveguide. The measured reflection coefficient is below −10 dB from 100 GHz to about...

Composition and size-dependent extinction coefficient of colloidal PbSe quantum dots

Iwan Moreels, Karel Lambert, David de Muynck, Frank Vanhaecke, Dirk Poelman, José C Martins, Guy Allan, Zeger Hens

Inductively coupled plasma mass spectrometry (ICP-MS) was combined with UV–vis−NIR spectrophotometry and transmission electron microscopy to determine the nanocrystal composition and molar extinction coefficient ϵ of colloidal PbSe quantum dot (Q-PbSe) suspensions. The ICP-MS results show a...
