Singularity dictates a device function at the nanoscale. Dopants or impurities, structural defects, adsorbates, and stray charges can behave as a singularity in certain conditions, either promoting or deteriorating the device function, which frequently is the major concern in the implementation of nanoscale memories and sensors.
In a nanodevice adopting nanomaterials, the control over singular points in the nanomaterials can be regarded as a tuning process of the device property, which may open up a new possibility of its application to the molecular measurements. In the earlier part of this talk, an example of the property-tuned nanodevice for molecular measurements will be discussed after a short introduction of visualizing the singularities in a nanodevice based on the nanomaterials.
An extreme case of the singularity can be found in a nanogap device which has two electrodes separated by a few to a few tens of nanometers. In the later part of this talk, application of nanogap devices in the electric/electrochemical (bio) molecular detection will be discussed with our recent experimental results along with the way of their simple lab-scale mass production.
