Photon induced near-field electron microscopy from nanostructured metallic films and membranes
Sophie Meuret, Hugo Lourenço-Martins, Sébastien Weber +2
We investigate - both experimentally and theoretically - the inelastic interaction between fast electrons and the electromagnetic field scattered by metallic apertures and nanostru…
Exciton spectroscopy and diffusion in MoSe2-WSe2 lateral heterostructures encapsulated in hexagonal boron nitride
Dorian Beret, Ioannis Paradisanos, Ziyang Gan +17
Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures with potential applications in optoelectronics. Critical for carrier…
Time-Resolved Cathodoluminescence in an Ultrafast Transmission Electron Microscope
S. Meuret, L. H. G. Tizei, F. Houdellier +6
Ultra-fast transmission electron microscopy (UTEM) combines sub-picosecond time-resolution with the versatility of TEM spectroscopies. It allows one to study the dynamics of materi…
Multiferroicity and colossal magneto-capacitance in Cr-thiospinels
J. Hemberger, P. Lunkenheimer, R. Fichtl +3
The sulfur based Cr-spinels RCr2S4 with R = Cd and Hg exhibit the coexistence of ferromagnetic and ferroelectric properties together with a pronounced magnetocapacitive coupling. W…
Apparent giant dielectric constants, dielectric relaxation, and ac-conductivity of hexagonal perovskites La1.2Sr2.7BO7.33 (B = Ru, Ir)
P. Lunkenheimer, T. Götzfried, R. Fichtl +5
We present a thorough dielectric investigation of the hexagonal perovskites La1.2Sr2.7IrO7.33 and La1.2Sr2.7RuO7.33 in a broad frequency and temperature range, supplemented by addi…
Experimental evidence for competition of antiferromagnetic and ferromagnetic correlations in HgCr2S4
V. Tsurkan, J. Hemberger, A. Krimmel +5
A detailed study of poly- and single crystalline samples of the normal spinel HgCr2S4 is reported. The structural refinement reveals enhanced values of the atomic displacements sug…
