Table 3 The carrier concentration and carrier mobility of the TCB-treated P3HT film in different directions and of the DC-P3HT film

From: Highly anisotropic P3HT films with enhanced thermoelectric performance via organic small molecule epitaxy

Different material

TCB-treated P3HT-parallel

TCB-treated P3HT-vertical

DC-P3HT

Carrier concentration (cm−3)

(6.4±0.8) × 1020

(4.4±0.6) × 1020

Electrical conductivity (S cm−1)

250±10

90±5

95±5

Carrier mobility (cm2 V−1 s−1)

2.5±0.3

0.9±0.1

1.3±0.2

  1. Abbreviation: TCB, 1,3,5-trichlorobenzene.
  2. The carrier mobility of TCB-treated P3HT film in the parallel direction is higher than that in the vertical direction and also higher than the mobility in DC-P3HT.
