Both the as-prepared and the purified SWCNT films exhibit nearly temperature-independent properties. With increasing pressure the low-energy absorbance decreases suggesting an increasing carrier localization due to pressure-induced deformations. The energy of the optical transitions in the SWCNTs decreases with incre","authors_text":"C. A. Kuntscher, F. Hennrich, K. Kamar\\'as, K.
