Semiconducting Carbon Nanotubes
The use of Raman spectroscopy to reveal the remarkable structure and properties of carbon nanotubes is briefly reviewed. Particular emphasis is given to the fact that a nanotube can be semiconducting or metallic depending on its diameter dt and chirality θ , and how Raman spectroscopy at the single nanotube level reveals such information. Some of the implications of the unusual properties of ca...
متن کاملPurification of semiconducting carbon nanotubes.
Since their discovery by Iijima in 1991, carbon nanotubes (CNTs) have attracted great interest in chemistry, physics, electronics, and materials science. As a result of their chemical and mechanical stability, high conductivity, high surfaceto-volume ratio, and other unique properties, CNTs have various potential applications in areas such as field-effect transistors (FETs), sensors, light emit...
متن کاملSemiconducting properties of cup-stacked carbon nanotubes
The current–voltage characteristics of individual cup-stacked carbon nanotubes (CSCNTs) were investigated in situ inside the transmission electron microscope. Different from other quasi-1D carbon structures such as multi-walled carbon nanotubes, carbon nanofibers or graphitic fibers that normally behave as a metallic conductor of electrons, individual CSCNTs were found to exhibit unexpectedly s...
متن کاملPhotothermoelectric effect in suspended semiconducting carbon nanotubes.
We have performed scanning photocurrent microscopy measurements of field-effect transistors (FETs) made from individual ultraclean suspended carbon nanotubes (CNTs). We investigate the spatial-dependence, polarization-dependence, and gate-dependence of photocurrent and photovoltage in this system. While previous studies of surface-bound CNT FET devices have identified the photovoltaic effect as...
متن کاملExciton dynamics in semiconducting carbon nanotubes.
We report a femtosecond transient absorption spectroscopic study on the (6, 5) single-walled carbon nanotubes and the (7, 5) inner tubes of a dominant double-walled carbon nanotube species. We found that the dynamics of exciton relaxation probed at the first transition-allowed state (E(11)) of a given tube type exhibits a markedly slower decay when the second transition-allowed state (E(22)) is...
