ZnO nanofibers were fabricated by electrospinning. The samples were characterized by Field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and Raman technique. Field emission scanning electron microscopy (FE-SEM) shows that the obtained ZnO nanofibers were randomly aligned on the substrates. XRD and Raman patterns show that the ZnO nanofibers is the wurtzite structure. The turn on electric field of the ZnO nanofibers for generating a current density of 10 μA/cm2 is 14 V/μm and the current density is over 1 mA/cm2 at an applied field of about 18.9 V/mm. The corresponding Fowler–Nordheim plot shows a linear behavior. The possible emission mechanism is discussed..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
