    • Bulk p-type BiSbTe alloy ingots were loaded into a jar with balls inside the argon-filled glove box to avoid oxidation of the nanopowder. The jar was loaded into a ball mill and processed for several hours. When the nanopowder was ready, it was loaded into 1.25- to 2.5-cm (inner diameter) dies and compacted into a 100% dense solid NC bulk sample by a hot press. Samples are available for testing upon request

    • We cut hot-pressed NC bulk pellets into blocks (2 mm by 3 mm by 1 mm) that were ground down into smaller blocks (2 mm by 3 mm by 0.002 mm) using a mechanical tripod polisher. We then glued the sample to a copper grid and milled it using a precision ion polishing system (Gatan Inc., Warrendale, Pennsylvania, USA) for 30 min, with incident energy of 3.2 kV and beam current of 15 μA at an incident angle of 3.5°.
