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 ...
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...
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...
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 ...
As for x > 0 the concentration of Li2O is constant, the ionic component of the DC conductivity, due to movement of Li+ ions, does not change significantly with increasing concentration of MoO3. However, degree of disorder increases with increasing concentration of MoO3 due to the creation of...
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...
