PDF | This paper reviews recent efforts in the literature to miniaturize nuclear battery systems. The potential of a nuclear battery for longer shelf-life and higher . PDF | Research groups at Cornell University and the University of Wisconsin have Their research involves developing devices, called nuclear microbatteries. atomic batteries by using nanomaterials to improve their performance. tomic batteries, nuclear batteries or radioisotope generators are devices.

The concerned p-n junction has 13 micro machine channels and the total junction area is The piece of piezoelectric material bonded to the top of the silicon cantilever bends along with it. Since it is not easy to micro fabricate solid radioactive materials, a liquid source is used instead for the micro machined p-n junction battery. This process will repeat as long as the source is active. It uses a process known as See-beck effect.

But all these approaches have some difficulties regarding low energy densities, elimination of by products, down scaling and recharging. All these difficulties can be overcome up to a large extend by the use of nuclear micro batteries.

Radioisotope thermo electric generators RTGs exploited the extraordinary potential of radioactive materials for generating electricity. RTGs are particularly used for generating electricity in space missions.

It uses a process known as See-beck effect. So the scientists had to find some other ways of converting nuclear energy into electric energy. They have succeeded by developing nuclear batteries.

Nuclear batteries use the incredible amount of energy released naturally by tiny bits of radio active material without any fission or fusion taking place inside the battery.

These devices use thin radioactive films that pack in energy at densities thousands of times greater than those of lithium-ion batteries. Because of the high energy density nuclear batteries are extremely small in size.

The word 'dainty' means pretty. Scientists have developed two types of micro nuclear batteries.

One is junction type battery and the other is self-reciprocating cantilever. The operations of both are explained below one by one. The kind of nuclear batteries directly converts the high-energy particles emitted by a radioactive source into an electric current. The device consists of a small quantity of Ni placed near an ordinary silicon p-n junction - a diode, basically. As the Ni decays it emits beta particles, which are high-energy electrons that spontaneously fly out of the radioisotope's unstable nucleus.

The emitted beta particles ionized the diode's atoms, exciting unpaired electrons and holes that are separated at the vicinity of the p-n interface. These separated electrons and holes streamed away form the junction, producing current. It has been found that beta particles with energies below KeV do not cause substantial damage in Si [4] [5].

The maximum and average energies The long half-life period years makes Ni very attractive for remote long life applications such as power of spacecraft instrumentation.

In addition, the emitted beta particles of Ni travel a maximum of 21 micrometer in silicon before disintegrating; if the particles were more energetic they would travel longer distances, thus escaping. These entire things make Ni ideally suitable in nuclear batteries.

Since it is not easy to micro fabricate solid radioactive materials, a liquid source is used instead for the micro machined p-n junction battery. The diagram of a micro machined p-n junction is shown below. As shown in figure a number of bulk-etched channels have been Micro machined in this p-n junction.

Compared with planar p-n Junctions, the three dimensional structure of our device allows for a substantial increase of the junction area and the macro machined channels can be used to store the liquid source. The concerned p-n junction has 13 micro machine channels and the total junction area is This is very important since the current generated by the powered p-n junction is proportional to the junction area.
