Zintl compounds exhibit promising thermoelectric properties {because of|due to|as a result of} the feasibility {of the|from the|in the|on the|with the|of your} chemical tuning of their electrical and thermal transport. {While|Whilst|Although|Even though|When|Though} most Zintl pnictides are {known|recognized|identified} to show p-type polarity, {recent|current} developments in high-performance n-type Mg3Sb2-based thermoelectric {materials|supplies|components} have encouraged {further|additional} identification of n-type Zintl pnictides. {In this|Within this} study, we demonstrate the bipolar dopability {of the|from the|in the|on the|with the|of your} Zintl arsenide Eu5In2As6. The electrical resistivity at 300 K with n-type polarity was decreased to 7.{6|six} x 10^-1 ohmcm {using|utilizing|making use of|employing|working with|applying} La as an electron dopant. In contrast {to the|towards the|for the} {relatively|fairly|comparatively|reasonably|somewhat} {high|higher} resistivity of n-type Eu5In2As6, the p-type resistivity at 300 K was decreased to {5|five}.9 x 10^-3 ohmcm {with a|having a|using a} carrier concentration of {2|two}.{8|eight} x 10^20 /cm3 {using|utilizing|making use of|employing|working with|applying} Zn as a hole dopant. This doping asymmetry is discussed {in terms of|when it comes to|with regards to} the weighted mobility of electrons and holes. {Furthermore|Moreover|In addition|Additionally}, {a very|a really|an extremely|an incredibly} low lattice thermal conductivity of 0.7 W/mK was observed at 773 K, {which is|that is|which can be} comparable to that {of the|from the|in the|on the|with the|of your} Sb-containing analogue Eu5In2Sb6. The dimensionless figure of merit ZT = 0.29 at 773 K for Zn-doped p-type Eu5In2As6.
