Four Probe Method (Basic Model)

The Four Probe Method is one of the standard and most widely used method for the measurement of resistivity of semiconductors.The experimental arrangement is illustrated. In its useful form, the four probes are collinear. The error due to contact resistance, which is specially serious in the electrical measurement on semiconductors, is avoided by the use of two extra contacts (probes) between the current contacts. In this arrangement the contact resistance may all be high compare to the sample resistance, but as long as the resistance of the sample and contact resistances are small compared with the effective resistance of the voltage measuring device (potentiometer , electrometer or electronic voltmeter), the measured value will remain unaffected. Because of pressure contacts, the arrangement is also specially useful for quick measurement on different samples or sampling different parts of the same sample.
Description of the experimental set-up

1. Probes Arrangement It has four individually spring loaded probes. The probes are collinear and equally spaced. The probes are mounted in a teflon bush, which ensure a good electrical insulation between the probes. A teflon spacer near the tips is also provided to keep the Resistivity of Semiconductor by Four Probe Method at different temperatures and determination of the Band-gap.probes at equal distance. The whole - arrangement is mounted on a suitable stand and leads are provided for the voltage measurement.

2. Sample Germanium crystal in the form of a chip (10X9X0.5mm)
3. Oven It is a small oven for the variation of temperature of the crystal from the room temperature to about 200°C (max.)

4. Four Probe Set-up, VT -02

The set-up consists of three units in the same cabinet.

(i) Multirange Digital Voltmeter

In this unit, intersil 31⁄2 digit single chip A/D

Converter ICL 7107 has been used. It has high accuracy like auto zero to less than 10μV, zero drift of less than 1μV/ °C, input bias current of 10pA max. and roll-over error of less than one count. Since the use of internal reference causes the degradation in performance due to internal heating, an external reference has been used.

(ii) Constant Current Generator

It is an IC regulated current generator to provide a constant current to the outer

probes irrespective of the changing resistance of the sample due to change in temperatures. The basic scheme is to use the feedback principle to limit the load currentof the supply to preset maximum value Variations in the current are achieved

by a potentiometer included for that purpose. The supply a highly regulated and practically ripple free d.c. source. The current is measured by the digital panel meter.
(iii) Oven Power Supply Suitable voltage for the oven is obtained through a step down transformer with a provision for low and high rates of heating. A glowing LED indicates, when the oven power supply is ‘ON’.
