“…These intermediate phases are intermetallic compounds and oen have large energy bandgaps. [31][32][33] These bandgaps act as the barriers to Na diffusion within the anode. Therefore, to understand the fast-charging capability of the CuS anode from a structural perspective, it is essential to identify the intermediate phases formed during reversible reactions the sodiation process.…”

“…AlSb is a recently studied material system for thermoelectric purposes. The system has been extensively studied for solar cells [6] and Li-ion batteries [7][8][9][10]. The synthesis of bulk single phase polycrystalline AlSb was recently reported by controlled melting [11] and mechanical alloying (MA) [12] followed by vacuum hot pressing (VHP).…”

Due to the sizably larger direct band gap of 2.26 eV of AlSb, the thermoelectric properties of intrinsic AlSb is considerably low. Despite a promising Seebeck coefficient, the low electrical conductivity and high thermal conductivity has limited the improvement of thermoelectric figure of merit. Replacing small amounts of Al by Mg can increase the number of holes in the solid-state, effectively helping tune the carrier concentration. This work explores the effect of Mg doping in AlSb. The incorporation of Mg at Al sites has increased the electrical conductivity without decreasing the Seebeck coefficient detrimentally. The thermoelectric figure of merit has shown improvement despite the large thermal conductivity observed. The work additionally explores the possibility of improving thermoelectric properties further by forming a composite with β-Zn 4 Sb 3. The highest thermoelectric figure of merit was found to be 0.075 at 873 K, which is 6 times higher than that in intrinsic AlSb.

“…Owing to this, the synthesis of bulk AlSb has proven to be very difficult in the past. Mechanical alloying (MA) has been used in the past to synthesize the intermetallic compound, but not much success has been achieved in terms of obtaining a single phase [3][4][5][6][7][8]. This could be largely due to the reasons stated above.…”

Aluminum antimonide is a semiconductor of the Group III-V order. With a wide indirect band gap, AlSb is one of the least discovered of this family of semiconductors. Bulk synthesis of AlSb has been reported on numerous occasions, but obtaining a single phase has always proven to be extremely difficult. This work reports a simple method for the synthesis of single-phase AlSb. Subsequently, consolidation was done into a near single-phase highly dense semiconductor in a form usable for thermoelectric applications. Further, the thermoelectric properties of this system are accounted for the first time. In addition, the mechanical properties of the intermetallic compound are briefly discussed for a possibility of further use.
