“…Previous studies on the conversion of 63 Ni beta particle energy into electricity by means of GaN-based p-n junctions reported output powers from 23 pW to 0.57 nW [2][3][4][5]. Note that, in practice, the power output is typically lower than theor etical expectations, which are often above 2 nW [6]. Similar experiments with silicon and SiC based devices using 63 Ni achieved output powers of around 15.4 pW [7] and 0.34 nW [8], though some silicon designs approached 9 nW [9].…”

GaN is a durable, radiation hard and wide-bandgap semiconductor material, making it ideal for usage with betavoltaic batteries. This paper describes the design, fabrication and experimental testing of 1 cm 2 GaN-based betavoltaic batteries (that achieve an output power of 2.23 nW) along with a full model that accurately simulates the device performance which is the highest to date (to the best of our knowledge) for GaN-based devices with a 63 Ni source.

“…Since the highest energy of the electrons emitted by the 3 H source is only 18.6 keV, energy loss modes such as displacement effects can be ignored, and the ionization effect is the main mode of energy loss. In this paper, the following method is used to calculate the ionization energy deposition [11][12][13][14], which is often used in this field.…”

In this paper, the Monte Carlo method and numerical model are used to build the electrical model of a SiC-based betavoltaic microbattery using a 3H source, and the influences of structural parameters and the surface recombination effect on the output characteristics of the SiC PN battery are simulated. According to Monte Carlo calculations based on the energy spectrum of the 3H source, the ionization energy deposition approaches the exponential distribution along the depth direction, and most of the 22rs are concentrated near the material surface. The ionization energy deposition data is converted into non-equilibrium carrier information for the numerical simulation of the battery’s output characteristics. The simulation results show that the conversion efficiency of the battery rises first, and then decreases with the increase of the doping concentration of the N region. This is because the N region-doping affects the depletion region width and the built-in electrical potential at the same time. After considering the surface recombination effect, the conversion efficiency decreased significantly. Thinning the thickness of or moderately reducing the doping concentration of the P region will weaken the surface recombination effect.

Radioluminescent nuclear battery containing CsPbBr ₃ quantum dots: Application of a novel wave‐shifting agent

et al. 2019

Summary Radioluminescent nuclear battery has been widely studied for its miniaturization and long life. In this study, all‐inorganic perovskite quantum dots (CsPbBr3 QDs) were selected as a novel wave‐shifting agent combined with liquid scintillator PPO (2,5‐diphenyloxazole). The QDs were used to regulate the emission spectrum to match different GaAs devices. The maximum output power of the RL nuclear battery was greatly enhanced by 1.91 to 2.53 times. Perovskite QDs with adjustable emission spectra were used as wave‐shifting agents and exhibited more excellent properties and application prospects than traditional wave‐shifting agents. The Monte Carlo method was used to simulate the energy deposition of fluorescent materials under various radioactive source models. Results verified the advantages of using liquid radioactive sources and liquid fluorescent materials. The application and reference value of perovskite QDs in nuclear detection and nuclear medical imaging were also discussed.
