四探针电阻与温度和栅极电压的报告之前和之后，在原位掺杂钾的单个单壁碳纳米管绳。所有的功能，在R（T）从无取向的散装材料，掺杂之前和之后，定性再现的绳索数据。原始绳的5.3It电导随着正栅压而减小，而K掺杂后G与V-g的关系变得无特征。
Four-probe resistance vs temperature and gate voltage are reported for an individual single-wall carbon nanotube rope before and after doping in situ with potassium. All the features in R(T) from unoriented bulk material, before and after doping, are qualitatively reproduced by the rope data. The 5.3 It conductance of the pristine rope decreases with positive gate voltage, while G vs V-g becomes featureless after K doping.
