Such contacting method provided mechanically stable
ohmic contact to the sample, which was then verified by thermal cycling over a wide range of temperatures.
In a part of [p.sup.+]n SCs, [n.sup.+]-Si film for back surface field (BSF) as well as
ohmic contact with back Ag electrode was grown on the back surface of Si wafer, with a thickness [d.sub.BSF] among 10 to 1000 nm.
To achieve a good
ohmic contact, the evaporated Ag was annealed at 500[degrees]C for 30 min.
In order to provide high isolation at higher frequencies, a shunt capacitive switch is provided after each
ohmic contact switch.
Yang and his colleagues also use a Z-scheme in their system only they deploy two Earth abundant and stable semiconductors - silicon and titanium oxide - loaded with co-catalysts and with an
ohmic contact inserted between them.
First, the influence of the soil and the
ohmic contact due to the soles of the shoes on the induced current density distribution is analyzed.
Electrodes on the back of these power devices have two purposes: To make
ohmic contact with Si substrates and to provide solder joints with heat sink substrates.
Contact resistivity is dependent on doping density, and it prevents the formation of good
ohmic contact because of surface state Fermi level pinning except the heavily doped regions in semiconductor.
