It is suggested that in YmoO_3 the triangular antiferromagnetic structure β precedes the α-type triangular antiferromagnetic structure found by neu- tron diffraction studies at 4.2K. the anomalous be- havior of the dielectric constant observed experimen- tally below the Neel temperature is ...
The analysis of the results of IR spectra have indicated that with increase in the content of MoO 3 there is an increasing degree of disorder in the glass network. The room temperature dielectric constant of these glass ceramics containing even the highest concentration of MoO 3 is always found...
This study demonstrates that asゞrown MoO3 has a high dielectric constant, κ, of ≈35 at room temperature at low frequencies by fabricating parallel plate capacitors from these thin flakes. Most importantly, mechanically exfoliated MoO3 nanoflakes are used to create heterostructures with WSe2 and...
Therefore, the threshold (usually 1–2 V) and switching (usually 3–5 V) voltages can be derived from this electrical modeling. At low voltages (below Vth) the capacitance is constant. A nonlinear variation of CLC is obtained if the voltage is increased. Finally, the device capacitance ...
X-ray diffraction examination of materials/ lattice parametersspace groupdielectric constantThe polycrystalline samples of Sm 2 (MoO 4 ) 3 have been prepared by heating appropriate quantities of oxides. The X-ray powder diffraction technique has been used to provide information about lattice parameter,...
The maximum barrier height was calculated and found to decrease by increasing MoO3 nanoparticle from 0.15 t0 0.12 eV. The analysis of the dielectric constant and dielectric loss suggested that their behavior can be explained by Maxwell–Wagner–Sillar type polarization at high frequency. At low ...

The sintering process, microstructure,dispersion character of initial permeability and dielectric constant of the low-temperature sintered Y-type hexagonal ferrites doped with BPb glass are reported.Experimental results show that complex Y -type hexaferrite containing Co, Zn and Cu(Ba2Me2Fe12O22, Me ...
However, further progress towards 2D electronics is hindered by factors such as the lack of a high dielectric constant (κ) dielectric with an atomically flat and dangling-bond-free surface3,4. Here, we report a facile synthesis of a single-crystalline high-κ (κ of roughly 16.5) van der...
Through sintering the Bi 2 O 3 –2.2MoO 3 at 620°C for 2 h, a composite dielectric containing both α and β phase can be obtained with a near-zero temperature coefficient of frequency TCF=13 ppm/°C and a relative dielectric constant r =35, and a large Q f 12000 GHz is also ...
