ZEPTOOLS Technology | From Graphene to Heterostructures: What Exactly Has Changed with Two-Dimensional Materials?

Imagine this: The macroscopic world we’re all familiar with—those sturdy concrete skyscrapers, conductive copper wires, or resilient rubber tires—seems to have properties that were “preordained” from the start. Concrete is strong because cement tightly binds sand and gravel together; rubber is elastic because polymer chains are cross-linked with one another. Yet over the past two decades, the field of materials science has uncovered a startling secret: When we shrink materials down to their absolute smallest scale—down to just a single atomic layer thick—those familiar physical rules we’ve long taken for granted undergo a dramatic transformation.

The Core Enabler of Quantum Chip Fabrication: Principles and Applications of Electron Beam Lithography

A quantum chip serves as the "brain" of a quantum computer, and its central role is akin to that of a central processing unit (CPU) in a conventional computer. However, unlike traditional chips, which rely on the operations of classical bits "0" and "1," quantum chips perform computations by leveraging the quantum mechanical properties of "quantum bits (Qubits)"—a feat made possible only with the precise support of electron beam lithography. Starting from the nature of quantum bits, this article analyzes their connection to electron beam lithography and explores how hybrid lithography techniques can address the challenge of mass-producing quantum chips.

ZEPTOOLS - The Effect of Charge Effect in Scanning Electron Microscopy (SEM) Observation and Its Elimination

Scanning electron microscopy (SEM) is a powerful observation tool widely used in materials science, biology and other fields. However, the charge effect is a common and unpleasant phenomenon during SEM observation and can negatively affect image quality. In this article, we will introduce the formation principle of the charge effect, its effect on the image, and the effective methods to eliminate the charge effect.
