Nearly‐Zero Thermal Expansion Along the Layer‐Stacking Axis of ZnSe‐Based Inorganic–Organic Hybrid Semiconductor Materials

Abstract

Zero thermal expansion (ZTE) is a desired but rare material property. Herein we report a unique family of inorganic-organic hybrid semiconductors with general formula [ZnSe-(L) 0.5 ] (L = organic diamine) that exhibit nearly-zero thermal expansion along the layer-stacking axis in the temperature range of 5-300 K. The unit cell parameters and crystal structures of [ZnSe(en) 0.5 ], [ZnSe(pda) 0.5 ], [ZnSe(bda) 0.5 ], and [ZnSe(ptda) 0.5 ] (en = ethylenediamine, pda = propanediam-[a]

From 1D Chain to 3D Network: A New Family of Inorganic–Organic Hybrid Semiconductors MO3(L)x (M = Mo, W; L = Organic Linker) Built on Perovskite-like Structure Modules

“…50,51 Materials exhibiting zero (or nearly zero) thermal expansion (ZTE) behavior are free from thermal shock on rapid heating or cooling. 52,53 Typically they are obtained by combining those of NTE and PTE type. The MO 3 (M = Mo, W) based hybrid structures exhibit interesting negative thermal expansion (NTE) behavior.…”

“…Most materials show positive thermal expansion (PTE) as they expand upon heating. Very few materials show negative thermal expansion (NTE) in which case they contract upon heating. , Materials exhibiting zero (or nearly zero) thermal expansion (ZTE) behavior are free from thermal shock on rapid heating or cooling. , Typically they are obtained by combining those of NTE and PTE type.

“…And both layers are stacked alternately in an ordered periodic way to form the layered structure. 15 Research of these hybrids has included studies on the intralayer structure, [14][15][16][17][18] thermal expansion behaviour, [19][20][21] pyrolysis properties, 22,23 energy band structure (by a DFT study), 24,25 photoelectric properties, [29][30][31] and applications have been found in white-light light emission diodes. [26][27][28] The room temperature UV optical absorption with a typical band edge exciton feature exhibited a large blueshi when compared with their II-VI semiconductor counterparts, which can be attributed to the strong quantum connement effect (QCE) 15 of the ME inorganic slabs, and the hybrid can be regarded as a periodic multiple quantum well (MQW) structure.…”
