# Nano radiation detector: A possibility Making Physically Useful Nanostructures With Focused Ion Beam: A study of Nano Gaps

## TL;DR

This paper explores geometric modifications to the Child-Langmuir law and introduces a nano-scale radiation detector capable of detecting radiation in very small volumes, advancing nanostructure-based detection technology.

## Contribution

It proposes a geometrical correction to the Child-Langmuir law and develops a novel nano-scale radiation detector for small volume applications.

## Key findings

- Child-Langmuir law shows geometric dependence in practice
- Capacitors' behavior varies with thickness and septation at nano scale
- A new radiation detector can operate in small volumes

## Abstract

Child-Langmuir law expresses the IV relation between two parallel plates. It has been found that in reality the ordinary Child Langmuir Law does not hold true. It shows some geometric dependence on the system.In this report capacitors of various thickness and septation has been studied both in macro and nano scale to propose a geometrical correction to the law. More over from the studies, a new type of radiation detector was prepared which can detect radiation in small volumes as compared with normal radiation detectors.
