Soft Chemistry, Coloring and Polytypism in Filled Tetrahedral Semiconductors: Toward Enhanced Thermoelectric and Battery Materials

“…The LiZnP prepared in this manner exhibits nanoscale particle sizes and colloidal stability. LiZnP is a particular interesting compound due to its suggested application in thermoelectrics, photovoltaics, Li‐ion batteries, and as a neutron detector . The bandgap and lattice constant of LiZnP are in good agreement with CdS, making the former an ideal low toxicity substitute for the latter …”

“…Li-based Nowotny-Juza phases typically adopt either the cubic MgAgAs-type or hexagonal LiGaGe-typec rystal structures ( Figure 1), which are most closely relatedt ot he zinc-blende and wurtzite frameworks, respectively.R ecently,L iZnP became the first filled tetrahedral semiconductor to be prepared by a low temperature, solution-phase method. [19] The LiZnP prepared in this manner exhibitsn anoscale particle sizes and colloidal stability.L iZnP is ap articular interesting compound due to itss uggested application in thermoelectrics, [20] photovoltaics, [21,22] Li-ion batteries, [23] and as an eutron detector. [24] The bandgapa nd lattice constant of LiZnP are in good agreement with CdS, making the former an ideal lowt oxicity substitute for the latter.…”

Synthesis and characterization of LiZnP and LiZnAs semiconductor material

“…Nowotny-Juza compounds were originally, and still today, studied for photonic applications [1][2][3]. The zincblende crystal structure is arranged where the group II atom is located at τ 1 ¼ (0, 0, 0)a where a is the lattice constant, and the group V atom is located at τ 2 ¼(1=4 , 1=4, 1=4)a.…”

“…The reaction produces a total Q-value of 4.78 MeV, shown in the following reaction, 6 Li þ 1 0 n-3 Hð2:73MeVÞþαð2:05MeVÞ ð 1Þ Many Nowotny-Juza compounds have been synthesized in the past, however, difficulties in synthesis, purification, crystal growth, and handling, unfortunately limit the available physical and electrical property data. These materials have traditionally been reacted in a one, or two-step process to synthesize the ternary material [1][2][3][4][5][6][22][23][24][25]. Ternary (LiZnP, LiZnAs) and binary materials (Li 3 As, Li 3 P) are not commercially available, and therefore require in-house techniques to acquire desired materials.…”

Static sublimation purification process and characterization of LiZnP semiconductor material

“…Finally, 6 Li has not been explored to the same extent as other thermal neutron absorbers, and has an intrinsic thermal neutron absorption cross section of 940 barns. The reaction produces a total Q-value of 4.78 MeV, seen in the following reaction, (1) Nowotny-Juza compounds were originally, and are still today, studied for photonic applications [16][17][18]. The zincblende crystal structure is arranged where the group II atom is located at τ 1 = (0, 0, 0)a where a is the lattice constant, and the group V atom is located at τ 2 = (1/4, 1/4, 1/4)a.…”
