Investigations of Phase Change Memory Properties of Selenium Doped GeTe and Ge2Sb2Te5
(2018-04-05)
GeTe and Ge2Sb2Te5 alloys are potential candidates for non-volatile phase change
random access memories (PCRAM). For electrical data storage applications the materials should have stable amorphous and crystalline phases, ...
Exchange Spring Behaviour in Magnetic Oxides
(2018-02-23)
When a permanent magnet is considered for an application, the quantity that quantifies the usability of that material is the magnetic energy product (BH)max. In today’s world, rare earth transition metal permanent magnets ...
Electrical Transport And Low Frequency Noise In Graphene And Molybdenum Disulphide
(2017-05-21)
This thesis work contains electrical transport and low frequency (1/f) noise measurements in ultrathin graphene and Molybdenum disulphide (MoS2) field effect transistors (FET). From the measurements, We mainly focus on the ...
Mechanical Properties and Self-Assembly of Nanostructures
(2017-12-12)
This thesis is devoted to the investigation of mechanical properties and self-assembly process of materials at the nanoscale. Various nanostructured materials such as nanoparticles, nanotubes, nanowires and thin films are ...
Study of Thermoelectric Properties of Lead Telluride Based Alloys and Two-Phase Compounds
(2018-01-03)
The growing need of energy worldwide has lead to an increasing demand for alternative sources of power generation. Thermoelectric materials are one of the ‘green energy sources’ which convert directly heat into electricity, ...
Optical, AC Conductivity, NMR and Raman Studies of Alkali Borogermanate Glasses
(2017-11-22)
Physical properties of materials and their constituents are interrelated. Though the
basic structural unit involved also plays a role in deciding the properties, this can be
manipulated to a certain extent, by carefully ...
Thermoelectric Propeties of Cu Based Chalcogenide Compounds
(2017-12-12)
Thermoelectric (TE) materials directly convert heat energy into electrical energy. The conversion efficiency of the TE devices depends on the performance of the materials. The conversion efficiency of available thermoelectric ...
Synthesis, Characterization and Electrical Transport In Carbon Nanotubes
(2011-08-05)
In this thesis, synthesis, characterization and electrical transport of Carbon nanotubes (CNTs) have been discussed. The first chapter contains a brief introduction of various forms of carbon including CNT. The CNTs are ...
