Measurement room temperature IV Transport Measurement System Specifications: Source and measurement units for 2-probe/4-probe DC electrical transport property measurements in the range of 1 milli-Ohm to 100 Mega-Ohm or better. All I and V measurements should be at least 6½ digit. All set-point resolution must be better than o.o5% of full-scale. Voltage Source ranges: 10V or better Voltage source set point resolution: at least 0.05% of full-scale Current source ranges: 100 micro Amperes, 1 milliAmperes, 10 milliAmperes or better Current source set point resolution: at least 0.05% of full-scale Voltmeter ranges: 100mV, 1 V, 10 V or better Voltmeter resolution: at least 6½ digit. Ammeter specification: 100 microAmperess, 1 milliAmperes, 10 milliAmperes or better Ammeter resolution: at least 6½ digit. Workbench for 2-probe/4-probe measurement with detachable sample stage. Data acquisition and control software, which automates recording of time-domain voltage, current and resistance data along with I-V, R-T measurements, allows easy control of all experimental parameters, supports real-time recording and plotting of physical quantities and runs on Linux or Windows. Non-linear IV (eg. diode characteristics) using dynamic switching between constant current and constant voltage source should be provided. Software should support temperature control and R-T measurements available through future system upgrades Detailed application notes illustrating varius experimental techniques used in IV measurement, with examples for the provided samples. All accessories required to run the system A computer system with lates specification and laserjet printer Upgrade: System shuould be upgradable to variable temperature measurement in the range of 80K to 450K using suitable temperature controller.
