Tailoring of optical, mechanical and surface properties of high-entropy Hf-Zr-Ce-Y-O ceramic thin films prepared by HiPIMS sputtering

Synthesis of chiral high-entropy sulfides for non-linear optical applications

“…However, for TM = Cu or Cu/Mn there is a clear trend that HEA mixing of the rare-earth cations enhances the SHG response while only slightly decreasing LDT, suggesting that this technique may be a viable strategy to enhance the NLO performance in reported materials. 44,45…”

“…However, for TM = Cu or Cu/Mn there is a clear trend that HEA mixing of the rare-earth cations enhances the SHG response while only slightly decreasing LDT, suggesting that this technique may be a viable strategy to enhance the NLO performance in reported materials. 44,45 To understand the trends in the NLO data, it is important to analyze the bonding within and between the different polyhedral units (Tables S2A-C † and Fig. 5).…”

Effect of the MgO Addition on the Structure and Physical Properties of the High Entropy HfZrCeYO Fluorite Ceramics

“…The same situation occurs for the ZrO 2 -Y 2 O 3 or HfO 2 -Y 2 O 3 systems [16]. There are several reports for the high-entropy HfO 2 -ZrO 2 -Y 2 O 3 -CeO 2 system, which crystallizes into a solid solution with a simple FCC cubic fluorite structure [11,13]. However, the thermal properties of this system have not yet been studied.…”

“…Identical effects of characteristic enhancement were reported for highentropy boride [5,6], carbide [10], nitride [7,8] and oxide [11] structures. Oxide-based high entropy ceramics (HEO) is one of the most promising materials among the variety of high-entropy ceramics [12], especially for ZrO 2 -and HfO 2 -based protective HEOs [13]. Considering a melting point of >2000 • C, there is a limited number of oxides that can be used for the UHTC applications [14].…”
