ABSTRACT150keV Si* ions and 160keV P* ions were implanted at 200°C with doses ranging from 5x1013 to 1x1015/cm2 to study the effect of dual implantations on the electrical properties of Fe doped InP. Samples encapsulated with Si3N4 films of about 1000Å were annealed in a halogen tungsten lamp RTA system under flowing N2 at different temperatures from 700 to 900°C for 5s. It has been found that Si*+P* dual implantations into InP can result in an enhanced activation, particularly significant at high dose of implantation. The maximum dopant activation and average electron mobility for Si*+P* dual implants at a dose of 1×1015/cm2 are 70% and 750cm2/vs, which corresponds to a peak electron concentration of 5×1019/cm3 while that for Si* single implant at the same dose are 29% and 870cm2/vs, which corresponds to a peak electron concentration of 1.2×10 19/cm3. The improvement of the electrical properties is discussed in terms of amphoteric behavior of silicon in InP.

In this study, adding CsPbI3 quantum dots to organic perovskite methylamine lead triiodide (CH3NH3PbI3) to form a doped perovskite film filmed by different temperatures was found to effectively reduce the formation of unsaturated metal Pb. Doping a small amount of CsPbI3 quantum dots could enhance thermal stability and improve surface defects. The electron mobility of the doped film was 2.5 times higher than the pristine film. This was a major breakthrough for inorganic quantum dot doped organic perovskite thin films.

ABSTRACTElectrical properties of thin (12 nm) SiO2 films with and without in-situ deposited poly Si electrodes have been studied. Thin SiO2 films were grown by the rapid thermal oxidation (RTO) process and the poly Si films were deposited by the rapid thermal chemical vapor deposition (RTCVD) technique at 675°C and 800°C. Good electrical properties were observed for SiO2 films with thin in-situ poly Si deposition; the flatband voltage was ∼ -0.86 V, the interface state density was < 2 × 1010/cm2/eV, and breakdown strength was > 10 MV/cm. The properties of RTCVD poly Si were also studied. The grain size was 10-60 rim before anneal and was 50-120 rim after anneal. Voids were found in thin (< 70 nm) RTCVD poly Si films. No difference in either SiO2 properties or poly Si properties was observed for poly Si films deposited at different temperatures.

ABSTRACTThe effect of the rapid thermal annealing (RTA) and hydrogenation step on the electronic properties of the n+ and p+ solid phase crystallized (SPC) poly-crystalline silicon (poly-Si) thin films was investigated using Hall effect measurements and four-point-probe measurements. Both the RTA and hydrogenation step were found to affect the electronic properties of doped poly-Si thin films. The RTA step was found to have the largest impact on the dopant activation and majority carrier mobility of the p+ SPC poly-Si thin films. A very high Hall mobility of 71 cm2/Vs for n+ poly-Si and 35 cm2/Vs for p+ poly-Si at the carrier concentration of 2×1019 cm-3 and 4.5×1019 cm-3, respectively, were obtained.
