Temperature effects on gallium arsenide Ni betavoltaic cell
A GaAs Ni radioisotope betavoltaic cell is reported over the temperature range 70 °C to −20 °C. The temperature effects on the key cell parameters were investigated. The saturation current decreased with decreased temperature; whilst the open circuit voltage, the short circuit current, the maximum power and the internal conversion efficiency values decreased with increased temperature. A maximu...

متن کاملWafer bonding of gallium arsenide on sapphire
Three-inch (100) gallium arsenide wafers were bonded to (1102) sapphire in a micro-cleanroom at room temperature under hydrophilic or hydrophobic surface conditions. Subsequent heating up to 500 ◦C increased the bond energy of the GaAs-on-sapphire (GOS) wafer pair close to the fracture energy of the bulk material. The bond energy was measured as a function of the temperature. Since the thermal ...
متن کاملGallium Arsenide - Based Readout Electronics
The readout of detector arrays requires the monolithic or hybrid integration of a integrate circuit multiplexer with the detector array. In most LWIR and VLWIR applications, a hybrid approach is used. For example, the detector array may be built from HgCdTe and the readout integrated circuit may be silicon CMOS [1]. The two integrated circuits are mated through a bump-bonding process in which e...
