Effects of substrates on the structure and dielectric properties of Ba(Sn0.15Ti0.85)O3 thin films

Effect of different buffer layers on the microstructure and dielectric properties of BaTiO3 thin films grown on Si substrates

“…However, it seems that the BTO film deposited on LNO/Si exhibit obviously larger loss tangent at higher frequencies than that of BTO film deposited on Pt/Ti/Si. This probably arises from the higher resistance of LNO films, leading to an increase in dielectric loss and a decrease in dielectric constant at higher frequencies [33], which also explains why the BTO/LNO/Si structure always shows stronger frequency dependent dielectric properties than BTO/Pt/Ti/Si. Meanwhile, at lower frequency of 600 Hz, it seems that the dielectric loss of BTO/LNO/Si is smaller than that of BTO/Pt/Ti/Si.…”

Ferroelectric composite artificially-structured functional material: multifield control for tunable functional devices

“…Most researchers focus on dielectric nonlinearity at kHz frequencies [89]. To reveal the mechanism of dielectric nonlinearity and develop applications at higher frequencies, it is meaningful to employ effective methods to study the dielectric nonlinearity at GHz, THz, or infrared frequency regions [90][91][92][93][94][95].…”

Dielectric Properties of Ba0.7Sr0.3TiO3 Film at Terahertz Measured by Metamaterials

“…BaTiO 3 ‐based ferroelectric materials exhibit inherently dielectric nonlinearity, continuously tunable dielectric constant at DC electric fields, and high power‐handling capability, which attract more and more attentions for applications in tunable devices. However, most studies have focused on their dielectric properties at kHz frequencies . To better understand the microscopic mechanism of their dielectric properties and expand their application scope at high frequencies, it is necessary to study the dielectric responses of ferroelectric materials at GHz and THz bands.…”
