  • The performance of GaInP/GaAs tandem solar cells with AlInP growth temperatures of 680$^{\circ}C$ and 700 $^{\circ}C$ on n-type GaAs (100) substrate with 2$^{\circ}$ and 6$^{\circ}$ tilt angles has been investigated. The series resistance and open circuit voltage of the fabricated tandem solar cells are affected by the substrate tilt angles and the growth temperatures of the window layer when zinc is doped in the tunnel diode. With carbon doping as a p-type doping source in the tunnel diode and the effort of current matching between top and bottom cells, GaInP/GaAs tandem solar cell has been exhibited 25.58% efficiency.

  • The theoretical and experimental current-voltage characteristics of Erbium silicided n-type Schottky barrier tunneling transistors (SBTTs) are discussed. The theoretical drain current to drain voltage characteristics show good correspondence and the extracted Schottky barrier height is 0.24 eV. The experimentally manufactured n-type SBTTs with 60 nm gate lengths show typical transistor behaviors in drain current to drain voltage characteristics. The drain current on/off ratio is about 10$^{5}$ at low drain voltage regime in drain current to gate voltage characteristics.
