Large magnetic-field-induced strains in Ni–Mn–Ga nonmodulated martensite
Large magnetic field-induced strains of up to 0.17% for a stress-free Ni53.1Mn26.6Ga20.3 single crystal with nonmodulated martensite phase were generated in a rotating magnetic field. This magnetic-fi...

We report a flexible paper transistor made with regenerated cellulose and covalently bonded multiwalled carbon nanotube (RC-MWCNT). MWCNT bonded to cellulose chains can act as electron channel paths in dielectric cellulose layers. It is found that the covalent bonding between cellulose and MWCNT can be modulated by reaction time and temperature. The RC-MWCNT paper transistor shows that the leakage current and the on/off ratio are strongly associated with the concentration of MWCNTs. The estimated electron mobility of RC-MWCNT paper is comparable to other organic transistor materials. The RC-MWCNT paper transistor has a potential for flexible electronic paper. ©2009 American Institute of Physics
