CdS films were prepared by chemical bath deposition (CBD) at 60 °C without stirring. The crystallographic structure of the films and the size of the crystallites in the films were studied by x-ray diffraction. The energy gap of the films was found to decrease by annealing. The best annealing temperature for CBD grown…

Enhanced interband tunnel injection of holes into a p-n junction is demonstrated using p-GaN/InGaN/n-GaN tunnel junctions with a specific resistivity of 1.2 × 10−4 Ω cm2. The design methodology and low-temperature characteristic of these tunnel junctions are discussed, and insertion into a p-n junction device is descr…

Tin sulphide films have been deposited onto glass substrates at room temperature by chemical bath deposition using aqueous solution. The structural and vibrational properties of the deposited films have been characterized by X-ray diffraction (XRD), FT-IR and Raman spectroscopy. XRD data indicate that as grown film is…

The effects of pH value on CdS thin films fabricated by using electrodeposition were investigated in detail. The pH values of the final solutions were adjusted between 1 and 5. Aqueous solutions of HCl and NaOH were used to adjust the pH. The reaction rates were changed by the pH due to the fact that the pH affected t…

This work describes the theoretical and experimental investigation of an in-house produced 63Ni radioisotope-powered GaN-based direct conversion (betavoltaic) nuclear battery. GaN p-n junction device with 1-mm2 area was fabricated and irradiated by the 63Ni plate source. Short-circuit current and open-circuit voltage…
