Three Reasons to Choose for Lightning

Reasons to Choose Lightning

The TEM in-situ thermoelectric system, Lightning, helps researchers observe the real-time dynamics of sample changes while precisely controlling the charging and heating environment.

The Nano-Chip in Lightning's sample bars utilizes a 4-point-probe method to accurately control voltage and temperature while acquiring meaningful data.

The unique design of the Nano-Chip allows the environmental conditions to be controlled individually or simultaneously to maximize voltage and temperature.

Reason 1

The highest environmental control in the world with a wide range of in-situ environmental stimuli

The ability to conduct experiments at high temperatures up to 1300°C and high voltages up to 150V, or to simultaneously deliver an electric field of 300kV/cm at 900°C, is the only product on the market that maximizes in situ environmental stimulation at high temperatures and high voltages.

Reason 2

High stability and low sample drift at high temperatures

The unique four-point heating method (4-point-probe method), as well as advanced technology and materials, maintains high reliability and stability at high temperatures and pressures. Even at temperatures up to 1000C (AT=1000C), the drift rate is less than 200 nm, and the sample stabilization time is short, so that high-quality imaging can be maintained over a long period of time.

Reason 3

A new viewing perspective, in situ high-resolution imaging

Measure IVs with true DA current sensitivity while performing thermal studies, and with a resolution of up to 60 pm, obtain clear atomic images to help researchers better understand the structure and properties of materials.

Testimonials

“In operando TEM observations provide a unique opportunity to visualise the correlations between the electrical properties and the structural changes. The exceptional stability of the DENSsolutions holder allows the in operando TEM experiments to be performed with atomic resolution. Recently, we successfully observed structural changes of resistive switching and organic-inorganic metal-halide perovskite solar cells devices while under electrical stimulus inside a TEM”

Dr. Martial Duchamp Nanyang Technological University
The ability to apply high electric-fields and to simultaneously perform high-resolution experiments at elevated temperatures is frankly impressive! The new and exciting possibilities that the DENSsolutions Lighting series offers trailblazing new directions at the forefront of materials research.”
