carrier mobility การใช้

• The most important parameter of OFET carrier transport is carrier mobility.
• The minority carrier diffusion constant is directly proportional to carrier mobility.
• Carrier mobility is most commonly measured using the Hall effect.
• Measured carrier mobilities for electrons and holes are shown in Figure 4.
• The carrier mobilities are much smaller than that of silicon.
• Thus lattice scattering lowers the carrier mobility more and more at higher temperature.
• HEMTs'exceptional carrier mobility and switching speed come from the following conditions.
• Even with extreme deformation, excellent carrier mobility in monolayer graphene can be preserved.
• Another important characteristic of these gels is that they maintain high charge carrier mobility.
• Measured charge carrier mobility exceeded / Vs.
• However, the extra impurities would reduce the carrier mobility so the resistivity would increase.
• Rubrene-based OFETs show the highest carrier mobility 20 40 cm 2 / ( V穝 ).
• These include the diffusion rate of dopant elements, carrier mobilities and the thermal production of charge carriers.
• Even for dopant concentrations in excess of 10 12 cm  " 2 carrier mobility exhibits no observable change.
• The term "'carrier mobility "'refers in general to both electron and hole mobility in semiconductors.
• Alternatively, if the carrier mobility is known, the diffusion coefficient may be determined from the Einstein relation on electrical mobility.
• In practical terms, a low effective mass leads directly to high carrier mobility, favoring higher speed of transport and current carrying capacity.
• Regarding perovskite materials, charge carrier mobility as high as 10 cm 2 V  " 1 s  " 1 has been observed.
• Upon transitioning to the Cmcm structure, SnSe maintains its low thermal conductivity but exhibits higher carrier mobilities, leading to its excellent ZT value.
• Rubrene holds the distinction of being the organic semiconductor with the highest carrier mobility, reaching 40 cm 2 / ( V穝 ) for holes.
