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 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
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, DFP-02
The set-up consists of three units in the same cabinet.
(i) Multirange Digital Voltmeter
In this unit, intersil 3½ 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.
Specifications:
- Range X1 (0-200mV) & X10 (0-2V)
- Resolution 100μV at X1 range
- Accuracy ±0.1% of reading ±1 digit
- Impedance 1MW
- Display 3½ digit, 7 segment LED (12.5mm height) with auto polarity and decimal indication Overload Indicator Sign of 1 on the left & blanking of other digits
(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 current of the supply to preset maximum value. Variations in the current are achieved by a potentiometer included for that purpose. The supply is a highly regulated and practically ripple free d.c. source. The current is measured by the digital panel meter.
Specifications:
- Open Circuit Voltage : 18V
- Current range : 0-20mA
- Resolution : 10μA
- Accuracy: ±0.25% of the reading ±1 digit
- Load regulation: 0.03% for 0 to full load
- Line Regulation: 0.05% for 10% changes
(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’. The experimental set-upis complete in all respect.

Study of Dielectric Constant and Curie Temperature of Ferroelectric Ceramics
Dielectric or electrical insulating material are understood as the material in which electrostic field can persist for long times. Layers of such substance are commonly inserted into capacitors to improve their perfomance, and the term dielectric refers specifically to this application. An electric field polarizes the molecules of dielectric producing concentrations of charge on its surface that create an electric field opposed (antiparallel) to that of capacitor. This reduces the electric potential. Considered in reverse, this means that, with a dielectric, a given electric potential causes the capacitor to accumulate a larger charge.
Applications
Beside the common and well known application of capacitors in electrical and electronic circuits, the capacitors with an exposed and porous dielectric can be used to measure humidity in air.
A huge leap in the research on dielectric (ferroelectric materials) came in 1950’s, leading to the wide spread use of Barium Titanate (BaTiO3-Perovskite Structure) based ceramics in capacitor applications and piezoelectric transducer devices. Since then, many other ferroelectric ceramics have been developed and utilized for variety of applications: various type of capacitors, non volatile memories in computers, etc.
Perovskite Structure
Perovskite is family name of a group of materials and the mineral name of calcium titanate (CaTiO3) having a structure of the type ABO3 (Fig 1)
A practical advantage of perovskite structure is that many different cations can be substituted on both A and B sites without changing the over all structure. Even though two cations are compatible in solution, their behaviour can be radically different when apart from each other. Thus it is possible to manipulate material’s properties such as Curie temperature or dielectric constant with only a small substitution of given cation.
All ferroelectric material have a transition called the Curie point (Tc). At T>Tc, the crystal does not exhibit ferroelectricity, while for T
Fig 2 shows the variation of dielectric constant (e) with temperature for Lanthanum doped Lead Zirconate Titanate (PLZT) ceramic, which is cooled from its paraelectric cubic phase to ferroelectric rhombohedral phase.

The "Stein Hall Viscosity Cup" is used in viscosity testing where the number of seconds required for a set volume of adhesive to flow through the viscometer's orifice. Viscosity is an important property of starch based adhesives and strongly affects bonding at the corrugator. Some pastes are too thick for certain paper and some are too thin, this is where viscosity testing is important. The apparent viscosity of adhesives used in the manufacture of corrugated container board is measured by the number of seconds required for 100 cc of adhesive to pass through an orifice in a disc. The readings obtained do not directly correspond with any other viscosity scale.

The excellent characteristics of AD549, ultra low bias current, low offset voltage, low drift and low noise have been fully utilized to obtain best results in the present picoammeter. The first operational amplifier AD549 is used in low level current to voltage configuration and the output has been directly read on a 3½ digit panel meter. The instrument is capable of accepting either polarity of the input current. Well regulated power supplies are incorporated to use the instrument upto 10% changes in a.c. main’s voltage.
Applications:
- Current from Photomultiplier tubes, Photometers etc.
- Leakage currents in solid state devices.
- FET gate and tube grid-voltage without loading errors
- Current through very high resistance’s in conjunction with a power supply
