Synthesis and properties of KTN films by sol-gel deposition and RF-magnetron sputtering

Epitaxially grown ferroelectric thin films for agile devices

“…Various methods were also carried out for KTN thin films deposition, like liquid-phase epitaxy [85], MOCVD [86,87], sol-gel methods [51][52][53]88] (including polymeric precursors [54,55]), radio frequency sputtering [56,89] and PLD [39,40,46,[90][91][92][93][94][95]. Most of these studies highlighted the difficulty to preserve the relationship between metal atoms according to the pseudo-binary diagram established for the synthesis of KTN single-crystals [45,85,96] or ceramics [16,44,97].…”

Growth and optical properties of KTa1−xNbxO3 thin films grown by pulsed laser deposition on MgO substrates

“…8,11 Thus, KTN is an attractive material for applications in various fields. Various methods were carried out for KTN thinfilms deposition like liquid phase epitaxy ͑LPE͒, 15 metalorganic chemical vapor deposition ͑MOCVD͒, 19,20 solgel method, 21-25 rf sputtering, 26,27 and pulsed laser deposition ͑PLD͒. 9,17,18 Indeed, one of the main difficulties of KTN thin-film synthesis is to preserve the potassium content and to avoid any pyrochloretype phase.…”
