Charging effects and anomalous resistive features of superconducting boron doped diamond films
Christopher Coleman, Somnath Bhattacharyya
Anomalous resistive peaks below the superconducting transition temperature in heavily boron doped nanocrystalline diamond films could have potential application in switching device…
Non-s wave superconductivity in boron-doped nanodiamond films with 0-π Josephson junction array
Somnath Bhattacharyya, Christopher Coleman, Davie Mtsuko +1
Superconducting transport properties of granular materials are greatly influenced by the microstructure. We show that in heavily boron-doped diamond films (HBDDF) films some sharp…
Observation of the Berezinskii-Kosterlitz-Thouless transition in Boron-doped diamond films
Christopher Coleman, Somnath Bhattacharyya
The occurrence of the Berezinskii-Kosterlitz-Thouless (BKT) transition is investigated in heavily boron-doped nanocrystalline diamond films through a combination of current-voltage…
Observation of quantum transport features in graphene devices fabricated utilizing a nano-manipulating probe technique
Christopher Coleman, Davie Mtsuko, Chris Botha +1
A novel method for fast fabrication of mesoscopic multilayered graphene electronic devices utilizing nanoprobes to exfoliate graphite flakes is developed. The magnetoresistance of…
Observation of Shubnikov de Haas and Aharanov-Bohm oscillations in silicon nanowires
Tahir Aslan, Davie Mtsuko, Christopher Coleman +2
We record fine oscillations of 20 to 60 mT superimposed on larger oscillations having periodicity ~ 2 T at temperatures up to 100 K and fields up to 10 T from silicon nanowires. Ha…
