We present fabrication of and the first measurements on partially suspended double quantum dots in a carbon nanotube. Our objective is to enhance the energy resolution for spectroscopy of the vibronic modes of a suspended nanotube. When fabricating our devices, nanotubes grown on‐chip are localized by AFM scanning, and subsequently contacted and gated with customized electrode geometries. First low‐temperature transport measurement results are discussed, where the double quantum dot characteristics are clearly recognizable in the measured current. In addition, we address current technological challenges and future plans. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
